Config this extension to shared_preload_libraries:

shared_preload_libraries = 'pg_search';

Create this extension with:

CREATE EXTENSION pg_search CASCADE; -- requires vector

Usage

Sources:

pg_search 0.25.2 adds ParadeDB’s full-text, structured, vector, and hybrid search index to PostgreSQL. Version 0.25 uses the paradedb index access method; the older bm25 access-method name remains a compatibility alias. The extension requires vector, supports PostgreSQL 15-18 upstream, and must be loaded through shared_preload_libraries.

Install and Build an Index

shared_preload_libraries = 'pg_search'

Restart PostgreSQL, then create the extension and a table with a stable unique key:

CREATE EXTENSION pg_search CASCADE;

CREATE TABLE documents (
  id          bigint PRIMARY KEY,
  title       text,
  body        text,
  category    text,
  embedding   vector(768)
);

CREATE INDEX documents_search_idx ON documents
USING paradedb (
  id,
  title,
  body,
  category,
  embedding vector_cosine_ops
)
WITH (key_field = 'id');

The key_field must be the first indexed column and uniquely identify every row. A text key must be indexed without tokenization. A table can have only one ParadeDB index, so include every searchable field in that index.

Full-Text Search

Use ||| to match any token and &&& to require all tokens:

SELECT id, title, pdb.score(id) AS score
FROM documents
WHERE body ||| 'postgresql search'
ORDER BY score DESC, id;

SELECT id, pdb.snippet(body) AS excerpt
FROM documents
WHERE body &&& 'postgresql indexing';

pdb.score(key_field) exposes the relevance score for the current row. pdb.snippet(indexed_text_column) returns a highlighted excerpt. These helpers are meaningful only in a query driven by a ParadeDB search predicate.

Vector Search

Vector indexing is beta in the 0.25 line and uses the vector type from pgvector. Choose the operator class when the index is created; changing the metric requires rebuilding the index.

SELECT id, title, embedding <=> $1::vector AS distance
FROM documents
WHERE id @@@ pdb.all()
ORDER BY embedding <=> $1::vector, id
LIMIT 20;

Supported index operator classes are vector_l2_ops, vector_ip_ops, and vector_cosine_ops. The 0.25 vector index does not index halfvec, sparsevec, or bit columns.

Hybrid Search

A single ParadeDB index can combine lexical predicates, structured filters, and vector ordering. For more elaborate fusion, use the documented RRF and weighted hybrid-search functions instead of adding scores from unrelated scales directly.

SELECT id, title, pdb.score(id) AS lexical_score
FROM documents
WHERE body ||| 'postgresql extension'
  AND category === 'database'
ORDER BY embedding <=> $1::vector, id
LIMIT 20;

Version 0.25.2 and Caveats

Version 0.25 renamed the primary index access method from bm25 to paradedb. Existing USING bm25 definitions remain supported, but new examples should use USING paradedb.
Version 0.25.1 supports deterministic vector tie breakers and pushes the vector arm of reciprocal-rank-fusion queries into the index. It also adds paradedb.vector_clustering_threshold, whose default is 500, and caps vector-index build parallelism at four workers.
Version 0.25.1 removes paradedb.vector_cluster_probe_epsilon and changes the vector-index bounds gate. After upgrading a database from 0.25.0, REINDEX every ParadeDB index that contains a vector field; installing the new shared library and running ALTER EXTENSION alone is not sufficient for those indexes.
Version 0.25.2 is a stability and correctness release. It fixes fieldless more_like_this with vector columns, pdb.fuzzy under generic prepared plans, orphaned dynamic filters, several parallel subplan and MPP plan-shape errors, and tightens access controls for typemod definitions. It adds no further index migration beyond the inherited 0.25.0 vector-index rebuild.
CREATE EXTENSION pg_search CASCADE can install the required vector extension, but every server process still needs the preload configuration and restart first. Loading it only with LOAD or session_preload_libraries is insufficient.
Query plans, tokenization, and ranking can change when an index is rebuilt with different field options. Test relevance and vector recall with production-shaped data before rollout.

PGroonga Documentation | GitHub: pgroonga/pgroonga

pgroonga_database is a sub-extension of the PGroonga project. It provides database management functionality for PGroonga, which makes PostgreSQL a fast full text search platform for all languages.

PGroonga is a comprehensive full text search solution that uses Groonga as a backend. It supports all languages including CJK (Chinese, Japanese, Korean) out of the box, and provides rich features such as:

Fast full text search with all language support
Rich query syntax (query language, script syntax)
JSON search
HTML/XML tag aware highlighting
Similar search
Synonym expansion
Autocomplete
Query log analysis

The PGroonga documentation is extensive and spans hundreds of pages. For detailed usage, API reference, operators, functions, and tuning guides, please refer to the official documentation site:

Quick Start

CREATE EXTENSION pgroonga_database;
CREATE EXTENSION pgroonga;

-- Create a table with text content
CREATE TABLE memos (
  id integer,
  content text
);

-- Create a PGroonga index
CREATE INDEX pgroonga_content_index ON memos USING pgroonga (content);

-- Insert data
INSERT INTO memos VALUES (1, 'PostgreSQL is a relational database management system.');
INSERT INTO memos VALUES (2, 'Groonga is a fast full text search engine that supports all languages.');
INSERT INTO memos VALUES (3, 'PGroonga is a PostgreSQL extension that uses Groonga as its backend.');

-- Full text search
SELECT * FROM memos WHERE content &@~ 'PostgreSQL OR Groonga';

Usage

pg_bigm Documentation | GitHub: pgbigm/pg_bigm

The pg_bigm module provides full text search capability in PostgreSQL. This module allows a user to create 2-gram (bigram) index for faster full text search.

pg_bigm is released under the PostgreSQL License, a liberal Open Source license, similar to the BSD or MIT licenses.

Features

Bigram indexing: Creates 2-gram (bigram) GIN indexes for text columns
Faster LIKE searches: Accelerates LIKE queries including prefix, suffix, and substring searches
All language support: Works with any language including CJK (Chinese, Japanese, Korean) without additional configuration
Simple API: Provides similarity search functions and operators

Functions and Operators

Functions

Function	Return Type	Description
`likequery(text)`	`text`	Generates a search query for full text search from a keyword
`show_bigm(text)`	`text[]`	Shows all 2-grams in the given string
`pg_gin_pending_stats(regclass)`	`record`	Returns the number of pages and tuples in the pending list of a GIN index

Operators

Operator	Description
`text =% text`	Returns true if the similarity between the left and right operands is greater than or equal to `pg_bigm.similarity_limit`

GUC Parameters

Parameter	Type	Default	Description
`pg_bigm.last_update`	`text`	-	Shows the last update date of the module (read-only)
`pg_bigm.enable_recheck`	`bool`	`on`	Controls whether recheck is performed during index scan
`pg_bigm.gin_key_limit`	`int`	`0`	Limits the maximum number of bigrams used for full text search. 0 means no limit
`pg_bigm.similarity_limit`	`real`	`0.3`	Sets the minimum similarity threshold for the `=%` operator

Examples

Basic Full Text Search

-- Create extension
CREATE EXTENSION pg_bigm;

-- Create a table with text data
CREATE TABLE documents (id serial PRIMARY KEY, content text);
INSERT INTO documents (content) VALUES
  ('PostgreSQL is a powerful database'),
  ('Full text search with bigram indexing'),
  ('Japanese text: 日本語テキスト検索');

-- Create a bigram index
CREATE INDEX docs_bigm_idx ON documents USING gin (content gin_bigm_ops);

-- Search using LIKE
SELECT * FROM documents WHERE content LIKE '%search%';

-- Search using likequery function
SELECT * FROM documents WHERE content LIKE likequery('database');

Similarity Search

-- Show bigrams for a string
SELECT show_bigm('PostgreSQL');

-- Similarity search
SET pg_bigm.similarity_limit = 0.2;
SELECT * FROM documents WHERE content =% 'database search';

Comparison with pg_trgm

pg_bigm has the following advantages over the built-in pg_trgm:

Feature	pg_bigm	pg_trgm
N-gram type	2-gram (bigram)	3-gram (trigram)
Minimum search string	1 character	3 characters
Non-alphabetic languages	Full support	Limited support
LIKE search types	Prefix, suffix, and substring	Prefix, suffix, and substring

For detailed documentation including advanced usage and performance tuning, see the official pg_bigm documentation.

Usage

GitHub: amutu/zhparser

zhparser is a PostgreSQL extension for full-text search of Chinese, based on the Simple Chinese Word Segmentation (SCWS) library.

Features

Chinese text segmentation for PostgreSQL full-text search
Built on the SCWS (Simple Chinese Word Segmentation) library
Supports custom dictionaries (TXT and XDB formats)
Database-level custom word tables (since v2.1)
Multiple tunable parameters for segmentation behavior

Quick Start

-- Create the extension
CREATE EXTENSION zhparser;

-- Create a text search configuration using zhparser
CREATE TEXT SEARCH CONFIGURATION chinese (PARSER = zhparser);

-- Add token type mappings
ALTER TEXT SEARCH CONFIGURATION chinese ADD MAPPING FOR n,v,a,i,e,l WITH simple;

-- Test Chinese text segmentation
SELECT to_tsvector('chinese', '小明硕士毕业于中国科学院计算所，后在日本京都大学深造');

-- Create a table and index for Chinese full text search
CREATE TABLE articles (id serial PRIMARY KEY, title text, body text);

CREATE INDEX articles_body_idx ON articles
  USING gin (to_tsvector('chinese', body));

-- Query with Chinese full text search
SELECT * FROM articles
  WHERE to_tsvector('chinese', body) @@ to_tsquery('chinese', '中国');

Configuration Parameters

zhparser provides several GUC parameters to control segmentation behavior:

Parameter	Default	Description
`zhparser.punctuation_ignore`	`off`	Ignore all punctuation
`zhparser.seg_with_duality`	`off`	Perform duality segmentation on long words
`zhparser.dict_in_memory`	`off`	Load the whole dictionary into memory
`zhparser.multi_short`	`off`	Short word compound segmentation
`zhparser.multi_duality`	`off`	Duality compound segmentation
`zhparser.multi_zmain`	`off`	Key word in first compound segmentation
`zhparser.multi_zall`	`off`	Use all compound segmentation

Token Types

zhparser supports the following token types from SCWS:

Code	Description
`a`	Adjective
`b`	Distinguishing word
`c`	Conjunction
`d`	Adverb
`e`	Exclamation
`f`	Position word
`g`	Root word
`h`	Prefix
`i`	Idiom
`j`	Abbreviation
`k`	Suffix
`l`	Temporary idiom
`m`	Numeral
`n`	Noun
`o`	Onomatopoeia
`p`	Preposition
`q`	Classifier
`r`	Pronoun
`s`	Locative word
`t`	Time word
`u`	Auxiliary
`v`	Verb
`w`	Punctuation
`x`	Unknown
`y`	Modal particle
`z`	State word

Custom Dictionaries

File-based Dictionaries

Place custom dictionary files in the share directory (typically $SHAREDIR/tsearch_data/):

TXT format: one word per line
XDB format: compiled SCWS dictionary format

Custom dictionaries take precedence over built-in dictionaries.

Database-level Custom Words (v2.1+)

-- Add custom words via zhparser's built-in table
INSERT INTO zhparser.zhprs_custom_word VALUES ('中国科学院计算所');

-- Reload custom dictionary (reconnect after sync to take effect)
SELECT sync_zhprs_custom_word();

-- Verify segmentation with custom word
SELECT to_tsvector('chinese', '小明硕士毕业于中国科学院计算所');

Install

Make sure PGDG and PIGSTY repo available:

pig repo add pgsql -u   # add both repo and update cache

Install this extension with pig:

pig install pg_bestmatch;		# install via package name, for the active PG version

pig install pg_bestmatch -v 18;   # install for PG 18
pig install pg_bestmatch -v 17;   # install for PG 17
pig install pg_bestmatch -v 16;   # install for PG 16
pig install pg_bestmatch -v 15;   # install for PG 15
pig install pg_bestmatch -v 14;   # install for PG 14

Config this extension to shared_preload_libraries:

shared_preload_libraries = 'pg_bestmatch';

Create this extension with:

CREATE EXTENSION pg_bestmatch;

Usage

How does it work?

Create an BM25 statistics based on your document set by bm25_create(table_name, column_name, statistic_name);. It will create a materilized view to record the stats.
Generate document sparse vector by bm25_document_to_svector(statistic_name, passage)
For query, generate query sparse vector bm25_query_to_svector(statistic_name, query)
Calculate the score by dot product between the query sparse vector and the document sparse vector
Currently we use huggingface tokenizer with bert-base-uncased vocabulary set to tokenize words. Might support more configuration on tokenizer in the future.

Install

CREATE EXTENSION pg_bestmatch;
SET search_path TO public, bm_catalog;

Example

Here is an example workflow demonstrating the usage of this extension with the example of Stanford LoCo benchmark.

Load the dataset. Here is a script for you if you want to experience pg_bestmatch with the dataset.

Create BM25 statistics for the documents table.

SELECT bm25_create('documents', 'passage', 'documents_passage_bm25', 0.75, 1.2);

Add an embedding column to the documents and queries tables and update the embeddings for documents and queries.

ALTER TABLE documents ADD COLUMN embedding svector; -- for pgvecto.rs users
ALTER TABLE documents ADD COLUMN embedding sparsevec; -- for pgvector users

UPDATE documents SET embedding = bm25_document_to_svector('documents_passage_bm25', passage)::svector; -- for pgvecto.rs users
UPDATE documents SET embedding = bm25_document_to_svector('documents_passage_bm25', passage, 'pgvector')::sparsevec; -- for pgvector users

(Optional) Create a vector index on the sparse vector column.

CREATE INDEX ON documents USING vectors (embedding svector_dot_ops); -- for pgvecto.rs users
CREATE INDEX ON documents USING ivfflat (embedding sparsevec_ip_ops); -- for pgvector users

Perform a vector search to find the most relevant documents for each query.

ALTER TABLE queries ADD COLUMN embedding svector; -- for pgvecto.rs users
ALTER TABLE queries ADD COLUMN embedding sparsevec; -- for pgvector users

UPDATE queries SET embedding = bm25_query_to_svector('documents_passage_bm25', query)::svector; -- for pgvecto.rs users
UPDATE queries SET embedding = bm25_query_to_svector('documents_passage_bm25', query, 'pgvector')::sparsevec; -- for pgvector users

SELECT sum((array[answer_pids] = array(SELECT pid FROM documents WHERE queries.dataset = documents.dataset ORDER BY queries.embedding <#> documents.embedding LIMIT 1))::int) FROM queries;

This workflow showcases how to leverage BM25 text queries and vector search in PostgreSQL using this extension. The Top 1 recall of BM25 on this dataset is 0.77. If you reproduce the result, your operations are correct.

Comparison with pg_search

pg_bestmatch.rs only provides methods for generating sparse vectors and does not support index-based search (which can be achieved by pgvecto.rs or pgvector).
pg_search performs BM25 retrieval via the external tantivy engine, which may have limitations when combined with transactions, filters, or JOIN operations. Since pg_bestmatch.rs is entirely native to Postgres, it offers full compatibility with these operations inside postgres.

Usage

GitHub: tensorchord/VectorChord-bm25

VectorChord-BM25 is a PostgreSQL extension for the BM25 ranking algorithm, implemented via Block-WeakAnd algorithms. It is designed to work together with pg_tokenizer for customized text tokenization.

Architecture

The extension comprises three main components:

Tokenizer: Converts text into bm25vector (sparse vectors storing vocabulary IDs and term frequencies)
bm25vector: A custom data type for storing tokenized text
bm25vector indexes: Accelerate search and ranking operations

Quick Start

-- Enable required extensions
CREATE EXTENSION IF NOT EXISTS pg_tokenizer CASCADE;
CREATE EXTENSION IF NOT EXISTS vchord_bm25 CASCADE;

-- Create a tokenizer (e.g., LLMLingua2 for English)
SELECT create_tokenizer('tokenizer1', $$
model = "llmlingua2"
$$);

-- Create a table with text content
CREATE TABLE documents (
  id SERIAL PRIMARY KEY,
  passage TEXT,
  embedding bm25vector
);

-- Tokenize text passages into bm25vectors
UPDATE documents SET embedding = tokenize(passage, 'tokenizer1');

-- Create a BM25 index
CREATE INDEX documents_embedding_bm25 ON documents USING bm25 (embedding bm25_ops);

-- Query with BM25 ranking
SELECT id, passage, embedding <&> to_bm25query('documents_embedding_bm25', tokenize('search query', 'tokenizer1')) AS score
FROM documents
ORDER BY score
LIMIT 10;

Note: BM25 scores in VectorChord-BM25 are negative, with more negative scores indicating greater relevance.

The `<&>` Operator

The <&> operator computes the BM25 relevance score between a stored bm25vector and a query bm25vector. Queries must be wrapped in to_bm25query() which takes the index name and the tokenized query:

-- Basic search query
-- to_bm25query(index_name, tokenized_query)
SELECT id, passage, embedding <&> to_bm25query('documents_embedding_bm25', tokenize('database system', 'tokenizer1')) AS score
FROM documents
ORDER BY score
LIMIT 10;

Language Support

VectorChord-BM25 supports multiple languages through different tokenizer configurations:

Language	Approach	Model/Pre-tokenizer
English	Pre-trained model	`model = "llmlingua2"` or `model = "bert_base_uncased"`
Chinese	Custom model with Jieba pre-tokenizer	`[pre_tokenizer.jieba]`
Japanese	Custom model with Lindera pre-tokenizer	Lindera with IPADIC dictionary
Custom	User-trained models via text analyzers	`create_custom_model_tokenizer_and_trigger()`

Chinese Text Search Example

Chinese text requires a custom model with a Jieba pre-tokenizer (not a pre-trained model):

-- Create a text analyzer with Jieba pre-tokenizer
SELECT create_text_analyzer('zh_text_analyzer', $$
[pre_tokenizer.jieba]
$$);

-- Create a custom model tokenizer that trains on your corpus
SELECT create_custom_model_tokenizer_and_trigger(
    tokenizer_name => 'zh_tokenizer',
    model_name => 'zh_model',
    text_analyzer_name => 'zh_text_analyzer',
    table_name => 'documents',
    source_column => 'passage',
    target_column => 'embedding'
);

Custom Tokenizer Models

For domain-specific terminology, you can create text analyzers with stopwords, stemming, and other filters, then train custom models on your corpus using create_custom_model_tokenizer_and_trigger().

Usage

GitHub: tensorchord/pg_tokenizer.rs

pg_tokenizer is a PostgreSQL extension that provides tokenizers for full-text search. It is designed to work with VectorChord-bm25 for native BM25 ranking index support.

Quick Start

CREATE EXTENSION pg_tokenizer;

-- Create a tokenizer using the LLMLingua2 model
SELECT create_tokenizer('tokenizer1', $$
model = "llmlingua2"
$$);

-- Tokenize text
SELECT tokenize('PostgreSQL is a powerful, open-source object-relational database system. It has over 15 years of active development.', 'tokenizer1');

Tokenizer Models

pg_tokenizer supports multiple tokenizer models for different languages and use cases:

Model	Language	Description
`llmlingua2`	English	BERT-based tokenizer from LLMLingua2
`jieba`	Chinese	Jieba Chinese text segmentation
`lindera/ipadic`	Japanese	Lindera tokenizer with IPADIC dictionary
Custom models	Any	User-trained models for domain-specific text

Creating Tokenizers

-- English tokenizer
SELECT create_tokenizer('en_tokenizer', $$
model = "llmlingua2"
$$);

-- Chinese tokenizer
SELECT create_tokenizer('zh_tokenizer', $$
model = "jieba"
$$);

-- Japanese tokenizer
SELECT create_tokenizer('ja_tokenizer', $$
model = "lindera/ipadic"
$$);

Tokenizing Text

-- Tokenize English text
SELECT tokenize('full text search in PostgreSQL', 'en_tokenizer');

-- Tokenize Chinese text
SELECT tokenize('PostgreSQL是一个强大的数据库系统', 'zh_tokenizer');

Text Analyzer

pg_tokenizer also provides text analyzer functionality that combines tokenization with additional text processing steps. For detailed text analyzer usage, refer to the Text Analyzer documentation.

Integration with VectorChord-BM25

pg_tokenizer is typically used together with VectorChord-BM25 for full BM25 ranking support:

CREATE EXTENSION IF NOT EXISTS pg_tokenizer CASCADE;
CREATE EXTENSION IF NOT EXISTS vchord_bm25 CASCADE;

-- Create a tokenizer
SELECT create_tokenizer('my_tokenizer', $$
model = "llmlingua2"
$$);

-- Tokenize text into bm25vectors for indexing and search
SELECT tokenize('your search query', 'my_tokenizer');

biscuit 3.0.0 is a PostgreSQL 16+ positional-bitmap index access method for exact LIKE and ILIKE filtering. It is strongest for anchored patterns, _ wildcards, length predicates, and multi-column conjunctions. Version 3.0.0 stores index state in WAL-logged relation pages, so crash recovery, point-in-time recovery, physical replication, and hot-standby reads use PostgreSQL’s ordinary recovery path. It does not require shared_preload_libraries or a restart.

The project remains under active development and recommends representative staging tests. Its per-connection memory, write amplification, and cache-reload behavior make it best suited to read-mostly analytical workloads rather than continuously updated OLTP tables or very large connection pools.

Build and Query an Index

Load the data first, then create the index. The default biscuit_ops supports both case-sensitive and case-insensitive predicates. Use biscuit_like_ops or biscuit_ilike_ops when only one mode is required, avoiding the unused structure set.

CREATE EXTENSION biscuit;

CREATE INDEX message_body_biscuit_idx
ON message USING biscuit (body biscuit_like_ops);

ANALYZE message;

EXPLAIN (ANALYZE, BUFFERS)
SELECT id, body
FROM message
WHERE body LIKE 'timeout%';

Expression and multi-column indexes are supported. The query must use expressions and operators compatible with the chosen operator class. Check representative plans after loading statistics, especially for unanchored patterns.

Operator Classes and Query Boundaries

biscuit_ops is the default text operator class and indexes LIKE, NOT LIKE, ILIKE, and NOT ILIKE.
biscuit_like_ops indexes only LIKE and NOT LIKE.
biscuit_ilike_ops indexes only ILIKE and NOT ILIKE.

Biscuit returns exact matches without a heap recheck, but it is a filtering index: it does not provide ordered, backward, index-only, or unique scans, cannot back CLUSTER, and does not support regular expressions, similarity search, fuzzy search, or locale-aware collation. A B-tree with text_pattern_ops is usually a better fit for selective prefix lookups, while pg_trgm is designed for unanchored substring, regular-expression, and similarity searches.

Diagnostics and Configuration

Important inspection objects include biscuit_indexes, biscuit_status, biscuit_index_stats(oid), biscuit_index_memory_size(), biscuit_pending_list_stats(oid), and biscuit_pending_list_usage. The memory function reports the current backend’s session-local copy. total_pending_bytes is refreshed during VACUUM, so pending-list figures can lag live writes by up to one vacuum cycle.

biscuit.delta_compaction_slots defaults to 20000 and controls how many pending rows are tolerated before compaction. It is a privileged setting because raising it can increase reload work for other sessions.
biscuit.diag_scan_trace defaults to off and emits verbose per-scan candidate accounting. Enable it only for a focused reproducer.

Every backend lazily loads its own copy of an index and keeps it for the connection lifetime. A committed write invalidates other cached copies; their next access reloads the index rather than refreshing it incrementally. Size pools for this memory behavior and avoid interleaving frequent writes with latency-sensitive reads.

Live-index INSERT and UPDATE generate substantial WAL; monitor pg_wal, replication lag, and replication-slot retention, and consider a bounded max_slot_wal_keep_size. Bulk loading before index creation is substantially cheaper. VACUUM drains pending work but does not shrink the index; use REINDEX to reclaim index space.

Upgrade to 3.0.0

Version 3.0.0 is an incompatible on-disk format change. Updating the extension catalog does not convert existing index pages: every Biscuit index created under 2.x must be rebuilt. Plan enough maintenance time and WAL capacity for the rebuild.

ALTER EXTENSION biscuit UPDATE TO '3.0.0';

SELECT schema_name, index_name
FROM biscuit_indexes;

REINDEX INDEX CONCURRENTLY public.message_body_biscuit_idx;

The unpatched upstream 3.0.0 archive ships and installs only the 2.5.0--3.0.0 step, while earlier stable packages exposed catalog versions 2.4.0 or 2.4.1. Pigsty’s 3.0.0 RPM and DEB packages restore that missing catalog path before applying the upstream step. For another source build or package, inspect pg_extension_update_paths('biscuit') before ALTER EXTENSION; regardless of the available SQL path, the mandatory REINDEX or REINDEX CONCURRENTLY remains a separate manual operation.

Install this extension with pig:

pig install pg_textsearch;		# install via package name, for the active PG version

pig install pg_textsearch -v 18;   # install for PG 18
pig install pg_textsearch -v 17;   # install for PG 17

Config this extension to shared_preload_libraries:

shared_preload_libraries = 'pg_textsearch';

Create this extension with:

CREATE EXTENSION pg_textsearch;

Usage

Sources: README v1.2.0, v1.2.0 release notes

pg_textsearch provides BM25-ranked full-text search for PostgreSQL with a bm25 access method and the <@> scoring operator. Upstream marks v1.2.0 as production ready.

v1.2.0 supports PostgreSQL 17 and 18. Prebuilt release assets are published for both PostgreSQL versions on Linux and macOS. The extension must be loaded through shared_preload_libraries before CREATE EXTENSION.

Enable the Extension

shared_preload_libraries = 'pg_textsearch'  # add to any existing list

CREATE EXTENSION pg_textsearch;

Install the new binary and restart PostgreSQL before running an extension upgrade:

ALTER EXTENSION pg_textsearch UPDATE;

The v1.2.0 release adds physical replication support and correctness fixes for update-heavy workloads. Install the matching binary and run the SQL extension upgrade before relying on the new version.

Build and Query BM25 Indexes

CREATE TABLE documents (id bigserial PRIMARY KEY, content text);

CREATE INDEX docs_idx
ON documents USING bm25(content)
WITH (text_config = 'english');

SELECT *
FROM documents
ORDER BY content <@> 'database system'
LIMIT 5;

<@> returns the negative BM25 score because PostgreSQL operator index scans are ascending; lower values are better matches. Use ORDER BY ... LIMIT for fast top-k searches.

For an explicit index reference, use to_bm25query():

SELECT *
FROM documents
ORDER BY content <@> to_bm25query('database system', 'docs_idx')
LIMIT 5;

The main documented SQL surface is:

text <@> 'query' to score text with planner-detected index context.
text <@> bm25query to score with an explicit bm25query.
to_bm25query(text) for ORDER BY use with planner-selected index context.
to_bm25query(text, text) for query text plus index name.
bm25query = bm25query for equality checks.

Index Options and Data Shapes

CREATE INDEX ON documents USING bm25(content)
WITH (text_config = 'english', k1 = 1.5, b = 0.8);

Index options are text_config (required), k1 (default 1.2), and b (default 0.75). Text search configurations such as english, simple, french, and german use PostgreSQL text search configuration names.

The extension supports native array input for text[], varchar[], and bpchar[] columns; array elements are concatenated before tokenization.

CREATE TABLE posts (id serial PRIMARY KEY, tags text[]);
CREATE INDEX posts_tags_idx ON posts USING bm25(tags)
WITH (text_config = 'english');

SELECT *
FROM posts
ORDER BY tags <@> 'database'
LIMIT 10;

Expression indexes support immutable text expressions, including JSONB extraction, text transformations, and multi-column concatenation:

CREATE INDEX events_msg_idx ON events USING bm25 ((data->>'message'))
WITH (text_config = 'english');

SELECT *
FROM events
ORDER BY (data->>'message') <@> to_bm25query('network error', 'events_msg_idx')
LIMIT 10;

Partial indexes scope search to a subset of rows. Query them with an explicit index name:

CREATE INDEX docs_en_idx ON docs USING bm25(content)
WITH (text_config = 'english')
WHERE lang = 'en';

SELECT *
FROM docs
WHERE lang = 'en'
ORDER BY content <@> to_bm25query('databases', 'docs_en_idx')
LIMIT 10;

Operations and GUCs

SELECT bm25_force_merge('docs_idx');
SELECT * FROM bm25_memory_usage();

bm25_force_merge(index_name) consolidates all segments into one and is best used after bulk loads, not during steady write traffic. bm25_memory_usage() reports shared memory usage for memtables.

Documented pg_textsearch GUCs in v1.2.0 include:

pg_textsearch.default_limit
pg_textsearch.compress_segments
pg_textsearch.segments_per_level
pg_textsearch.memory_limit
pg_textsearch.bulk_load_threshold
pg_textsearch.memtable_spill_threshold (deprecated; use memory_limit for new deployments)

pg_textsearch.memory_limit defaults to 2GB and caps dynamic shared memory used by memtables. The README also documents bm25_spill_index(index_name), bm25_dump_index(index_name), and bm25_summarize_index(index_name) as development or diagnostic helpers.

Caveats

pg_textsearch requires shared_preload_libraries = 'pg_textsearch' and a PostgreSQL restart before CREATE EXTENSION.
The bm25 access method name conflicts with pg_search and vchord_bm25; avoid installing those BM25 access-method extensions into the same database.
Inside PL/pgSQL and stored procedures, the implicit text <@> 'query' form does not use planner hooks; upstream says to use to_bm25query() with an explicit index name there.
Phrase queries are not native because the index stores term frequencies, not term positions; use BM25 ranking plus a post-filter for phrase-like matching.
Partial indexes require to_bm25query() with the index name because the implicit query form skips them.
BM25 indexes on partitioned tables use partition-local statistics, so cross-partition scores may not be directly comparable.
Words longer than PostgreSQL’s tsvector word length limit are ignored during tokenization.
pg_textsearch uses fixed LWLock tranche IDs 1001-1008; another extension using the same fixed IDs can make wait-event names inaccurate.

Install

Make sure PGDG and PIGSTY repo available:

pig repo add pgsql -u   # add both repo and update cache

Install this extension with pig:

pig install pg_pinyin;		# install via package name, for the active PG version

pig install pg_pinyin -v 18;   # install for PG 18
pig install pg_pinyin -v 17;   # install for PG 17
pig install pg_pinyin -v 16;   # install for PG 16
pig install pg_pinyin -v 15;   # install for PG 15
pig install pg_pinyin -v 14;   # install for PG 14

Create this extension with:

CREATE EXTENSION pg_pinyin;

Usage

Sources:

pg_pinyin romanizes Chinese text and exposes tokenizer and query helpers for search applications. Use pg_pinyin to create stable Pinyin search keys, tokenize Han text, or expand Pinyin input into a pg_search regular-expression query.

Version 0.0.5 is primarily a packaging and toolchain update; its upgrade script makes no SQL catalog changes, so the user-facing API remains compatible with 0.0.4.

Create the Extension

CREATE EXTENSION pg_pinyin;

The extension is relocatable and does not require shared_preload_libraries or a server restart.

Romanize Text

Romanize character by character or use word-aware segmentation:

SELECT pinyin_char_romanize('重庆');
SELECT pinyin_word_romanize('重庆火锅');
SELECT pinyin_word_romanize('重庆火锅', ' ');

Both functions accept an optional suffix inserted after each emitted Pinyin unit. Character mode is deterministic per character; word mode uses the bundled word dictionary to resolve contextual pronunciations.

Use pg_search Tokenizer Input

Word romanization also accepts a pg_search tokenizer result when that extension is available:

SELECT pinyin_word_romanize(
  description::pdb.icu::text[]
)
FROM documents;

The overload returns romanized text; it does not expose a row-per-token API. Use the plain-text overload when pg_search tokenization is not required.

Build a pg_search Query

When pg_search was installed before pg_pinyin, pg_pinyin provides a typed overload that returns pdb.query:

SELECT *
FROM documents
WHERE id @@@ pinyin_regex_phrase(
  'chong qing',
  slope => 1,
  max_expansions => 64,
  generated_pinyin => true
);

If pg_search is absent, the same entry point is installed as an error-reporting stub rather than silently returning a different type. Install dependencies in the intended order and test the function signature after upgrades.

Object Index

pinyin_char_romanize(text [, suffix]) returns character-based Pinyin text.
pinyin_word_romanize(text [, suffix]) returns dictionary-segmented Pinyin text.
pinyin_word_romanize(tokenizer_input [, suffix]) accepts a pg_search tokenizer result.
pinyin_regex_phrase(text, slope, max_expansions, generated_pinyin) constructs a pg_search Pinyin phrase query when that integration is available.
pinyin_regex_phrase_patterns is an internal pattern-building helper; prefer the public query function.

Operational Notes

The extension ships generated character and word dictionaries in its pinyin schema. Treat those tables as extension-managed data rather than application tables. Romanization is normalization, not translation, and ambiguous or domain-specific readings may require application-side review.

Usage

Sources:

pg_kazsearch provides Kazakh full-text stemming for PostgreSQL 16 through 18. It installs a ready-to-use kazakh_cfg configuration and pg_kazsearch_dict dictionary. Cyrillic and supported modern Latin-script Kazakh converge to canonical Cyrillic stems so documents and queries can match across scripts.

Core Workflow

CREATE EXTENSION pg_kazsearch;

SELECT ts_lexize('pg_kazsearch_dict', 'алмаларымыздағы');
-- {алма}

SELECT to_tsvector('kazakh_cfg', 'мектептеріміздегі оқушылардың');
-- 'мектеп':1 'оқушы':2

Add a weighted stored vector and GIN index:

ALTER TABLE articles ADD COLUMN fts tsvector
GENERATED ALWAYS AS (
    setweight(to_tsvector('kazakh_cfg', title), 'A') ||
    setweight(to_tsvector('kazakh_cfg', body), 'B')
) STORED;

CREATE INDEX articles_fts_idx ON articles USING GIN (fts);

SELECT title
FROM articles
WHERE fts @@ websearch_to_tsquery('kazakh_cfg', 'президенттің жарлығы')
ORDER BY ts_rank_cd(
    fts,
    websearch_to_tsquery('kazakh_cfg', 'президенттің жарлығы')
) DESC;

Dictionary Tuning

Penalty weights can be changed at runtime:

ALTER TEXT SEARCH DICTIONARY pg_kazsearch_dict
    (w_deriv = 3.5, w_short_char = 100.0);

The default script_mode = auto detects supported modern Kazakh Latin orthography and returns Cyrillic stems. Disable Latin handling when strict Cyrillic-only behavior is required:

ALTER TEXT SEARCH DICTIONARY pg_kazsearch_dict
    (script_mode = cyrillic_only);

Upgrade and Search Caveats

Stemmer upgrades change index terms. After upgrading to 2.3.0, recompute stored tsvector columns or repopulate trigger-maintained vectors, then VACUUM (ANALYZE) the table.

ALTER EXTENSION pg_kazsearch UPDATE;
UPDATE articles SET title = title;
VACUUM (ANALYZE) articles;

Long-lived sessions opened before an upgrade should reconnect so they load the new dictionary.
Latin support targets the modern orthography. Mixed-script input, legacy apostrophe/acute/digraph spellings, and low-confidence ASCII tokens may remain unchanged.
websearch_to_tsquery uses strict AND semantics for ordinary terms. Applications that need broader recall should deliberately implement and measure a fallback query rather than silently changing all searches to OR.

Usage

Sources: README v0.4.13, API reference, query semantics, input types, index parameters, index policy

psql_bm25s is a PostgreSQL-native index access method for BM25-family lexical retrieval. It keeps the BM25 contract explicit through corpus-statistics-driven ranking, exact top-k retrieval APIs, and PostgreSQL storage/maintenance behavior for mutable tables.

Version 0.4.13 is packaged for PostgreSQL 17 and 18 in this catalog.

Basic Search

CREATE EXTENSION psql_bm25s;

CREATE TABLE docs (
    id integer PRIMARY KEY,
    title text NOT NULL,
    body text NOT NULL
);

INSERT INTO docs (id, title, body) VALUES
    (1, 'red apple', 'fresh red apple fruit'),
    (2, 'green apple', 'green apple slices'),
    (3, 'orange citrus', 'orange citrus fruit'),
    (4, 'cat guide', 'small cat animal care');

CREATE INDEX docs_bm25_idx
    ON docs USING psql_bm25s (body);

SELECT d.id, d.title, h.score
FROM psql_bm25s_query(
    'docs_bm25_idx'::regclass,
    'apple fruit',
    5
) AS h
JOIN docs AS d ON d.ctid = h.ctid
ORDER BY h.score DESC, d.id;

With no WITH (...) options, the index uses Lucene-style BM25 and IDF defaults with the realtime consistency policy.

Indexed Inputs

psql_bm25s supports five indexed source-column types:

text and varchar for direct indexing of ordinary scalar text columns.
text[] and varchar[] for application-owned token streams.
int4[] for applications that manage token IDs externally.

Scalar text and varchar columns are tokenized at the index boundary. Pretokenized arrays avoid scalar retokenization and are the preferred shape when the application already owns tokenization.

Retrieval APIs

The canonical exact BM25 APIs are:

psql_bm25s_query_tokens(regclass, text[], k, weight_mask) for token-text indexes.
psql_bm25s_query_ids(regclass, int4[], k, weight_mask) for token-ID indexes.

The main SQL convenience APIs are:

psql_bm25s_query(regclass, query_text, k, weight_mask, ...)
psql_bm25s_prepared_query(regclass, query_text, ...)
psql_bm25s_query_prepared(prepared_query, k, weight_mask)

These rowset APIs return psql_bm25s_result_hit rows with ctid, doc_id, and score. Join hits back to application rows with ctid when the query needs both row data and the query-time score.

Operators

The operator surface is useful for SQL-native filtering and ordering:

tokens @@ 'query text' is a boolean document-match predicate.
tokens @@@ psql_bm25s_prepared_query(...) is an index-bound prepared predicate.
ORDER BY tokens <=> psql_bm25s_order_tokens(...) ASC LIMIT k is the ordered retrieval form.

@@ is not a ranking API. <=> aligns with true BM25 ordering only when PostgreSQL chooses a real psql_bm25s index scan; use the rowset retrieval APIs when you need the clearest exact top-k contract.

WITH rq AS (
    SELECT psql_bm25s_ranked_query(
        'docs_bm25_idx'::regclass,
        'apple fruit',
        10
    ) AS q
)
SELECT d.*
FROM docs AS d, rq
WHERE d.body @@@ psql_bm25s_filter_query(rq.q)
ORDER BY d.body <=> psql_bm25s_order_tokens(rq.q) ASC
LIMIT (rq.q).k;

Index Options

Scoring reloptions include:

method and idf_method, defaulting to lucene; supported variants are robertson, lucene, atire, bm25l, and bm25+.
k1, default 1.5.
b, default 0.75.
delta, default 0.5, used by BM25L and BM25+.

Scalar text processing reloptions include:

text_lowercase, default true.
text_stopwords, default NULL.
text_stem_english, default false.
text_fold_diacritics, default false.

CREATE INDEX docs_body_bm25_idx
    ON docs USING psql_bm25s (body)
    WITH (
        method = 'lucene',
        idf_method = 'lucene',
        k1 = 1.5,
        b = 0.75,
        text_stem_english = true
    );

Multi-Field and Hybrid Search

For separate title, abstract, and body indexes, use late fusion helpers so each field produces query-scoped hits before scores are combined:

SELECT d.id, d.title, h.score
FROM psql_bm25s_fusion_query(
    ARRAY[
        'docs_title_bm25_idx'::regclass,
        'docs_body_bm25_idx'::regclass
    ],
    'apple fruit',
    ARRAY[3.0, 1.0]::real[],
    10,
    30,
    NULL
) AS h
JOIN docs AS d ON d.ctid = h.ctid
ORDER BY h.score DESC, d.id;

Hybrid vector/BM25 search is also a late-fusion layer. BM25 and vector indexes produce candidates independently, and psql_bm25s_hybrid_fuse_candidates(...) combines them using rrf by default. The core extension does not require pgvector, VectorChord, or any vector type to be installed.

Maintenance and Cache

The public maintenance switch is the consistency reloption:

realtime, the default, keeps committed writes searchable immediately.
eventual favors foreground read/write latency and allows short-term stale BM25 results while maintenance converges.
manual leaves refresh under explicit operator or scheduler control.

Operational helpers include:

psql_bm25s_index_details(regclass)
psql_bm25s_index_policy_recommend(regclass, profile)
psql_bm25s_index_refresh(regclass)
psql_bm25s_index_maintain(regclass)
psql_bm25s_index_try_maintain(regclass)
psql_bm25s_index_maintain_due(max_indexes)

Large immutable index payloads can use a shared generation cache. The zero-configuration DSM cache does not require shared_preload_libraries. For large connection-pool deployments, an optional shared-preload arena can be enabled with shared_preload_libraries = 'psql_bm25s' and psql_bm25s.shared_generation_cache_size, but that arena is not required for normal use.

Related global GUCs include:

psql_bm25s.maintenance_worker_limit
psql_bm25s.preload_timer_interval_ms
psql_bm25s.maintenance_timer_interval_ms
psql_bm25s.maintenance_rebuild_memory_budget

Caveats

The extension is not relocatable after creation; choose a non-public schema at CREATE EXTENSION time if needed.
eventual and manual consistency deliberately trade immediate freshness for lower foreground cost or explicit refresh control.
Logical replication follows PostgreSQL behavior: table rows replicate, but index relations do not replicate as logical data objects, so indexes should be created or rebuilt on subscribers.
The optional shared-preload cache requires PostgreSQL configuration and a restart because the shared arena is allocated at server start.

Source Tarball

pg_fts-0.2.0.tar.gz

pig build pkg pg_fts;		# build rpm/deb

Install

Make sure PGDG and PIGSTY repo available:

pig repo add pgsql -u   # add both repo and update cache

Install this extension with pig:

pig install pg_fts;		# install via package name, for the active PG version

pig install pg_fts -v 18;   # install for PG 18
pig install pg_fts -v 17;   # install for PG 17

Create this extension with:

CREATE EXTENSION pg_fts;

Usage

Sources:

pg_fts provides BM25/BM25F full-text ranking through dedicated ftsdoc and ftsquery types and an fts inverted-index access method. It supports boolean, phrase, NEAR, prefix, fuzzy, and regular-expression terms while keeping corpus statistics in the index for relevance scoring. Version 0.2.0 requires PostgreSQL 17 or newer.

Create and Query an Index

CREATE EXTENSION pg_fts;

CREATE TABLE docs (
    id bigint PRIMARY KEY,
    body text NOT NULL
);

CREATE INDEX docs_fts
ON docs USING fts (to_ftsdoc('english', body));

Use the same text-search configuration for documents and ordinary query terms:

WITH q AS (
    SELECT to_ftsquery('english', 'postgres & "query planner" & index*') AS query
)
SELECT d.id,
       fts_snippet(d.body, q.query) AS excerpt
FROM docs AS d
CROSS JOIN q
WHERE to_ftsdoc('english', d.body) @@@ q.query
ORDER BY to_ftsdoc('english', d.body) <=> q.query
LIMIT 10;

@@@ matches, while ascending <=> distance orders rows by descending relevance and can drive an index ordering scan for top-k queries.

Query Language and API Index

to_ftsdoc([regconfig,] text) and to_ftsquery([regconfig,] text): analyze documents and parse queries.
quick brown, quick & brown, quick | brown, and !slow: implicit/explicit AND, OR, and NOT.
"quick brown", NEAR(...), term*, term~2, and /regular-expression/: phrase, proximity, prefix, fuzzy, and regex terms.
fts_bm25, fts_bm25_opts, and fts_bm25f: explicit BM25 scoring variants and multi-field scoring.
fts_index_stats(index) and fts_index_df(index, query): index-maintained document count, average length, vocabulary size, and term frequencies.
fts_highlight and fts_snippet: present matching text.
fts_search(index, query, k) and fts_count(index, query): index-native top-k and MVCC-aware count operations.
tsquery_to_ftsquery(tsquery): migration helper; it does not make pg_fts a transparent replacement for tsvector/GIN.

Maintenance and Version Caveats

SELECT fts_merge('docs_fts');
SELECT fts_vacuum('docs_fts');

Inserts enter an immediately matchable pending list, but ranked <=> and fts_search results cover merged segments. Run fts_merge() when newly inserted documents must participate in ranking immediately.
fts_vacuum() compacts segments and truncates reclaimable index pages; ordinary VACUUM also participates in pending-list and tombstone maintenance.
Version 0.2.0 renamed the access method from bm25 to fts. Indexes created by 0.1.0 with USING bm25 must be recreated.
If the library reports an on-disk format mismatch, follow its REINDEX hint rather than attempting to read the index with a different format version.
The access method is non-covering and does not provide parallel scans in this release. Provision the extension and index separately on logical-replication subscribers; indexes themselves are not logically replicated.

Create this extension with:

CREATE EXTENSION pg_cjk_parser;

Usage

Sources:

pg_cjk_parser is a PostgreSQL full-text-search parser derived from the built-in parser. In a UTF-8 database it keeps the default behavior for non-CJK text while emitting overlapping 2-gram tokens for Chinese, Japanese, and Korean text. The extension installs parser support functions; you create the text-search parser and configuration that use them.

Core Workflow

CREATE EXTENSION pg_cjk_parser;

CREATE TEXT SEARCH PARSER public.pg_cjk_parser (
    START = prsd2_cjk_start,
    GETTOKEN = prsd2_cjk_nexttoken,
    END = prsd2_cjk_end,
    LEXTYPES = prsd2_cjk_lextype,
    HEADLINE = prsd2_cjk_headline
);

CREATE TEXT SEARCH CONFIGURATION public.config_2_gram_cjk (
    PARSER = public.pg_cjk_parser
);

SELECT alias, description, token
FROM ts_debug(
    'public.config_2_gram_cjk',
    'PostgreSQL 全文検索和中文检索'
);

Use the configuration explicitly in generated tsvector columns and queries, or set it as the session default:

SET default_text_search_config = 'public.config_2_gram_cjk';

SELECT to_tsvector('public.config_2_gram_cjk', '日本語全文検索');

Important Objects

prsd2_cjk_start, prsd2_cjk_nexttoken, prsd2_cjk_end, prsd2_cjk_lextype, and prsd2_cjk_headline: support functions used by CREATE TEXT SEARCH PARSER.
cjk_zht2zhs(text): converts mapped Traditional Chinese characters to Simplified Chinese while leaving other characters unchanged.
Parser token type cjk: emits overlapping CJK bigrams; CJK punctuation is emitted as a unigram.

SELECT cjk_zht2zhs('漢語');
-- 汉语

Version Notes and Caveats

Version 0.1.0 fixes incorrect cjk_zht2zhs scanning across mixed-width UTF-8 characters and corrects handling of four-byte CJK code points.
Upstream supports PostgreSQL 11 through 18 at this release.
The database must use UTF-8 for CJK bigram behavior. With another encoding, the parser behaves like the PostgreSQL default parser.
Creating a text-search parser requires elevated privileges. Decide mappings, dictionaries, stop words, and ranking separately; the example configuration defines only the parser.

CREATE EXTENSION pg_jieba;

Usage

Sources:

pg_jieba adds Jieba-based Chinese word segmentation to PostgreSQL full-text search. The upstream v2.0.1 source release installs SQL extension version 1.1.0, as recorded by its control file. It provides separate document and query parsers plus ready-to-use text-search configurations.

Core Workflow

CREATE EXTENSION pg_jieba;

SELECT to_tsvector(
    'jiebacfg',
    '小明硕士毕业于中国科学院计算所，后在日本京都大学深造'
);

SELECT plainto_tsquery('jiebaqry', '云计算专家');

Use jiebacfg to build searchable document vectors and jiebaqry to segment user queries:

ALTER TABLE articles
ADD COLUMN search_vector tsvector
GENERATED ALWAYS AS (to_tsvector('jiebacfg', body)) STORED;

CREATE INDEX articles_search_idx
ON articles USING GIN (search_vector);

SELECT title
FROM articles
WHERE search_vector @@ plainto_tsquery('jiebaqry', '中文全文检索');

Object Index

jieba: document text-search parser.
jiebaqry: query-oriented text-search parser.
jiebacfg: document text-search configuration using jieba and jieba_stem.
jiebaqry: text-search configuration of the same name using the query parser.
jieba_stem: simple dictionary with Jieba stop words used for the parser’s token categories.

Custom Dictionary and Caveats

Upstream reads a custom dictionary named jieba.user.dict.utf8 from PostgreSQL’s tsearch_data directory. Entries may contain a word and optional part-of-speech tag:

云计算
韩玉鉴赏
蓝翔 nz

The v2.x source requires a C++11-capable compiler because of its bundled cppjieba dependency.
Upstream’s published compatibility testing is old and limited. Build and regression-test the package against the exact PostgreSQL major version used in production.
Changing dictionaries changes tokenization. Recompute stored tsvector values and rebuild dependent indexes when dictionary output changes.
