How does hybrid search fix RAG problems?

Combines vector similarity with SQL filters like dates and permissions in one optimized query, pruning junk before expensive scans.

Is hybrid search ready for production RAG?

Yes, if your DB supports vector columns and indexes — pgvector, MyScale, or enterprise heavies nail it now.
