Partially VerifiedClaude Code adopts an 'Agentic Search' approach, operating directly on the local file system and using grep to search and trace reference chains, rather than relying on a central index.70% similarUnverifiedVector retrieval relies on vector databases for fuzzy matching and cannot precisely express structural relationships, whereas graph retrieval uses graph databases as the storage medium and is specifically optimized for multi-hop traversal queries.58% similarUnverifiedVector databases such as Pinecone, Weaviate, and Chroma can complete semantic similarity code retrieval at the millisecond level via approximate nearest neighbor (ANN) algorithms.58% similarUnverified当数据库规模较大时需要做Schema裁剪，根据用户问题只检索相关表结构，避免超出模型的上下文窗口限制55% similar
