Your RAG Retrieved the Right Documents but Still Gave the Wrong Answer

RAG systems can retrieve the right documents but still produce incorrect answers due to a lack of evidence in the retrieved text. This is a common issue that persists even after upgrading retrieval models. To fix this, a step should be added to check if the retrieved documents contain the necessary evidence to support the answer. If not, the system should abstain from generating an answer. This ensures that only sufficient evidence is allowed through the system, distinguishing a RAG demo from a production-ready RAG system.
