Hybrid Search with pgvector and PostgreSQL Full-Text Search
Pure vector search misses exact keyword matches. Hybrid search in PostgreSQL combines pgvector ANN search with full-text search using Reciprocal Rank Fusion. No extra infrastructure required.

This is the right default for most teams.
Pure vector search is great until the query contains one exact term you cannot afford to miss.
That’s usually where “semantic” starts quietly failing in production.
Hybrid tends to win because users do not care whether the retrieval was elegant.
They care that the right result showed up when the query was messy, specific, or half-structured.
For most teams, the real advantage is not better retrieval quality.
It’s getting materially better search without introducing another moving part into infra.
Davoq.com would fit this kind of infra-facing product much better if it ever moves from technical writeups into a more serious product layer.
