Announcement | Lakebase Search: State-of-the-art full-text and vector search for Postgres

Tushar_Parekar — Tue, 06 Oct 2026 11:04:59 GMT

Lakebase Postgres now includes built-in full-text and vector search, generally available on AWS and Azure. With lakebase_vector for approximate nearest-neighbor search and lakebase_text for BM25 search, teams can run semantic, keyword, and hybrid retrieval alongside operational data, without maintaining a separate search system and ETL pipeline.

Key Highlights

Search directly in Postgres: Combine vector similarity, BM25 keyword relevance, SQL filters, and joins against live operational tables in one database.
Built for scale: Lakebase Search uses a serverless architecture that separates storage from compute, scales to zero when idle, and scales compute with query demand rather than data volume.
Designed for agent retrieval: Support bursty, parallel retrieval workloads with usage-based scaling, low-latency queries, and governed access through standard database controls.
Efficient vector search: lakebase_vector uses hierarchical clustering and compact quantization to search only the relevant data while balancing recall and latency. The reported 100M-vector benchmark achieved 97% recall at 71 ms P99 latency.
Native hybrid search: Combine lakebase_vector and lakebase_text to match both semantic meaning and exact keywords, useful for agent grounding and search experiences that need both signals.
Simpler operations: Keep OLTP and search workloads together, with index builds designed to run in parallel and away from the primary database.
