The laptop return that broke a RAG pipeline
Summary

The retrieval accuracy gap in RAG systems occurs when vector similarity retrieves stale policy documents or mis-scoped content, as semantic closeness doesn't ensure factual correctness. Hybrid search—a single query merging vector similarity with SQL predicates—addresses this by letting the database optimizer apply structured filters before vector scans, avoiding inefficient two-phase filtering.
