LEANN is better suited to internal retrieval where the knowledge base is large but query frequency is low and latency is not sensitive, to resource-constrained edge or single-machine deployments, and to experimental environments that require frequent index rebuilds.

UnverifiedMulti-hop queries need to traverse multiple information nodes in a step-by-step manner, and vector retrieval is ill-suited for such scenarios due to its lack of a relational dimension.78% similarUnverifiedRead-intensive strategies may cause context overflow or cost spikes when handling large codebases, while search-first strategies achieve a better balance between information completeness and token efficiency.72% similarUnverified文档型数据库结构松散可能导致后期维护困难，需重视查询性能优化如索引设计72% similarUnverifiedFull-context injection avoids index staleness drift and retrieval missing key passages, but the cost is consuming tokens on every call, so it is only suitable for small-scale knowledge bases; large and dynamic knowledge bases must rely on retrieval.72% similar
