Neon 自吃狗粮：文档搜索全部改用自家 Lakebase Search 等 AI 组件
matei_zaharia · x · 2026-10-27
Neon replaced its hosted search vendor and rebuilt neon.com docs search fully on its own primitives: Lakebase Search extensions, Neon Functions, Neon AI Gateway, and Lakebase Postgres.
Key components:
- lakebasevector: pgvector-compatible, with an index needing a fraction of HNSW memory (under 10 GB for 100M vectors vs 300 GB for HNSW), scaling past a billion vectors
- lakebasetext: brings BM25 to Postgres, weighing term rarity and document length unlike native tsrank, returning top results without scoring every match
Both ship new index types (lakebaseann, lakebasebm25) designed for Neon's compute/storage-separated architecture. A full dogfooding writeup of hybrid vector+BM25 search in Postgres.
