Debugging RAG: Prioritize Retrieval Before Prompt Tuning

This article provides a debugging strategy for addressing incorrect answers from Retrieval-Augmented Generation (RAG) systems. It emphasizes separating retrieval failures from generation failures by first logging the retrieved chunks. If the correct information is not present in the retrieved chunks, the focus should shift to the indexing and chunking process rather than prompt tuning. The article suggests checking if documents were ingested correctly, if content was lost during parsing, or if chunks lack sufficient context, recommending structure-aware chunking or hybrid search methods to improve retrieval accuracy.
