pgvector
Store vector embeddings alongside relational data, then combine similarity matching with ordinary database filters. A practical starting point for semantic and hybrid search.
The useful part
Store vector embeddings alongside relational data, then combine similarity matching with ordinary database filters. A practical starting point for semantic and hybrid search.
Who it helps
Developers building search over an existing PostgreSQL catalogue.
Put it to work
Start with a small labeled retrieval set. Compare exact keyword results with vector results and measure their combined ranking before increasing index complexity.
Know the limits
Vector similarity does not establish factual correctness. Memory, filtering behavior and retrieval quality need workload-specific measurement.
