Builds a hybrid retrieval pipeline that enforces tenant scope before ranking, assembles a bounded context, and verifies returned citations.
Combines exact lexical matching with semantic recall and explains why hybrid retrieval often needs measured fusion and ranking.
Balances retrieval precision, answer completeness, document structure, overlap, metadata, and model input limits.
Rebuilds and compares incompatible vector spaces using versioned indexes, shadow queries, atomic cutover, and rollback.
Defines embeddings as model-produced vectors used for similarity and contrasts representation with text generation.
Uses pre-filtering for authorization and hard constraints while recognizing engine-specific recall and performance behavior.
