RAG · RETRIEVAL STACK

A RAG system needs more than a vector database

The vector index supplies proximity. A defensible stack adds exact search, filters, permissions, reranking and verification.

A bright retrieval architecture passes from exact search through metadata and permission filters into a small vector index and through reranking to an ordered evidence packet.
01 · FINDCreate lexical and semantic candidates through suitable routes.
02 · CONTROLCheck validity, version, metadata and permission before generation.
03 · RANKFuse, reorder and assemble results into evidence.
CORE METHOD

ROUTE → FILTER → RETRIEVE → FUSE → RERANK → ASSEMBLE → VERIFY

Relevance arises from signals; authority arises from rules, provenance and verification.

THE RETRIEVAL STACK TEST

Compare ten questions using vector, lexical and hybrid search. Measure recall, permissions and freshness.
