## Notes

pg_textsearch is a PostgreSQL extension for ranked full-text search with BM25 scoring. It is written in C and loaded by the Postgres server, so the server has to be restarted after the extension is added. The [README](https://github.com/timescale/pg_textsearch/blob/main/README.md) names the PostgreSQL releases it supports and gives two install routes: prebuilt binaries from the releases page, and a build from source with make.

Timescale, Inc., which does business as Tiger Data, maintains the project.

## Worth knowing

Tiger Data also offers the extension on its managed service, Tiger Cloud.

The project was originally named Tapir, so its older name may still appear in other sources.
