Retrieval systems find relevant documents from large corpora to support generation or analysis. Posts cover HyDE hypothetical document embedding, self-RAG reflection, CRAG corrective retrieval, and the retrieval patterns that improve answer quality in RAG-powered applications.

Lesson 4 of Harness Engineering in Go — three collaborating stores (a thread, a knowledge index, and a summarizer) behind interfaces, and an honest accounting of where each local stand-in leaks.
Lesson 4: memory is three stores, not one — an append-only thread, a keyword knowledge index, and a lossy first-and-last summarizer — and an honest account of where each local stand-in leaks against Azure.
Embedding a question and embedding an answer often produce different vectors. HyDE generates a hypothetical answer to the question, embeds *that*, and retrieves on it. Retrieval quality goes up disproportionately.
Naive RAG retrieves on every query. Self-RAG decides whether to retrieve. CRAG decides whether the retrieved content is good enough or needs corrective retrieval. Two papers; both worth implementing.
