UnverifiedIn a legal-scenario RAG system, when the retrieved results are insufficient to support an answer, the system must explicitly refuse to answer; this is a core function, not a system limitation.79% similarUnverifiedCommon RAG mistakes include improper chunking strategies, mismatch between the embedding model and queries, and lack of reranking on retrieved results.79% similarUnverifiedA failed RAG question-and-answer interaction may stem from multiple independent failure points, including the data layer, the comprehension layer, the generation layer, and the orchestration layer.78% similarUnverifiedThe original post proposed that the three hurdles for RAG in production environments are: answer filtering based on user permissions, traceability of the answer generation process, and output contradictions caused by inconsistency across multiple data sources.77% similarUnverifiedIn a RAG system, if the document parsing stage loses summary rows due to the merged-cell problem, that information will not exist in the vector database, and subsequent retrieval and generation cannot restore it.77% similar
