Report #25373

[frontier] Vector similarity retrieves semantically similar but logically unrelated chunks

Use knowledge graph-based retrieval \(GraphRAG\) to capture relational context and community structure for multi-hop reasoning queries

Journey Context:
Naive RAG fails on questions requiring connections across documents \('Who reported to the manager who implemented X?'\). GraphRAG builds communities of entities and relationships, then uses global search across communities. It costs significantly more upfront \(indexing into graph communities\) but eliminates hallucinations from chunk boundary issues and enables global reasoning.
