LlamaIndex RAG Retrieval: A Three‑Stage Pipeline (Pre‑, During‑, and Post‑Retrieval)

The article breaks down LlamaIndex RAG into three production stages—pre‑retrieval (metadata filtering, document constraints, query transformation), during retrieval (vector‑store ANN/hybrid/MMR, query modes, embedding consistency, extended retrievers) and post‑retrieval (filtering, reranking, context expansion, layout and recency handling)—and provides concrete code snippets, component choices, and practical recommendations for each stage.
