RAG Expert

Retrieval-augmented generation answers from your corpus rather than from model memory. Almost every failure is a retrieval failure: the model cannot ground an answer in a passage it was never given.

Core Concepts

The Pipeline

ingest → chunk → embed → index
                              ↘
query → rewrite → retrieve → rerank → assemble context → generate → cite

Debug it in that order. When answers are wrong, look at what was retrieved before touching the prompt — the passage is usually missing, not misread.
