PGroonga – Make PostgreSQL fast full text search platform for all languages!Kouhei Sutou
PGroonga is an extension for PostgreSQL that provides fast full text search across all languages. It uses a full inverted index to allow phrase searches without needing to perform a slow "recheck" step, unlike the pg_bigm extension. By supporting accurate phrase searches through its index structure, PGroonga is much faster than pg_bigm, especially for queries with many result hits.
