Pg_textsearch is a PostgreSQL extension that adds BM25 relevance-ranked full-text search with simple SQL syntax. It integrates with native text search configurations, supports partitioned tables, and targets modern Postgres versions for scalable, in-database text ranking.

What to expect from an ideal product
- Install the pg_textsearch extension directly into your PostgreSQL database to get BM25 ranking without external search engines or complex setup
- Use familiar SQL syntax to write text search queries that automatically return results ordered by BM25 relevance scores instead of random order
- Connect the extension to PostgreSQL's built-in text search configurations so your existing search setups work with improved ranking right away
- Run BM25-ranked searches across partitioned tables to handle large datasets while maintaining fast, relevant results at scale
- Get proper relevance scoring for full-text searches that works natively inside PostgreSQL without moving data to separate search systems
