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.

How to Efficiently Incrementally Update Knowledge in RAG Applications

Incremental knowledge updates in Retrieval‑Augmented Generation (RAG) systems can be achieved by using document‑level or chunk‑level strategies, leveraging hash fingerprints, record managers, and framework‑specific APIs such as LangChain’s index() with cleanup modes or LlamaIndex’s ingestion pipeline, reducing redundant computation and cost.
