Term Kind Topic What it is
Hybrid Retrieval Dense + Sparse Retrieval, BM25 + Vector pattern RAG Architecture Running lexical keyword search and dense vector search together and fusing the results, because each fails where the other succeeds.
Retrieval Grounding Grounded Generation concept RAG Architecture Constraining a model's answer to content retrieved from an authoritative corpus, with citations and an abstention path - so that output quality becomes a retrieval problem rather than a model problem.
Retrieval Pipeline Stages pattern RAG Architecture The stages that turn a user question into grounded context — query processing, retrieval, reranking and assembly — each independently tunable.
Retrieval-Generation Separation Evaluate Retrieval Independently, Two-Stage Debugging practice RAG Architecture Measuring whether the correct passage was retrieved, separately from whether the answer was correct - the single diagnostic that turns unfalsifiable RAG debugging into a specific measurable defect.
