Hi all, I built pg_kazsearch, a PostgreSQL extension that adds full-text search support for Kazakh. Currently there's no Kazakh dictionary, stemmer, or stop word list available in PostgreSQL, so anyone searching Kazakh text is stuck with trigram matching or application-level workarounds.
Kazakh is agglutinative — a single word can carry 5-6 suffixes, which makes standard search approaches miss most relevant results. pg_kazsearch provides a custom Kazakh stemmer (core written in Rust), a stop word list, and a text search dictionary that plugs into the standard PostgreSQL FTS infrastructure — GIN indexes, ts_rank, phrase search all work out of the box. I tested it on a dataset of 3,000 real Kazakh news articles. On the same query, pg_kazsearch returns 61 relevant articles vs 1 with trigram search, with a 23% improvement in recall overall. You can install it with a single command via deb package or Docker image, no compilation needed.

Thanks, Darkhan
