Announcing Native BM25 Ranking in AlloyDB and Cloud SQLgoogle.com

Google Cloud adds native BM25 ranking to AlloyDB and Cloud SQL (PostgreSQL 17+) via the open‑source pg_textsearch extension, letting you run keyword‑based full‑text search inside the database. This removes the need for a separate search backend and, on AlloyDB, speeds up vector queries up to 10×.
