Unverified50% confidenceDecision RuleExact time
In RAG systems, the most similar results returned by vector retrieval do not necessarily mean sufficiently similar; a similarity threshold (e.g., 0.7) should be set to filter out retrieval results below the threshold, preventing the LLM from generating misleading answers by forced association.
