Report #85261
[frontier] Vector search returns disconnected facts that agents cannot synthesize into complex multi-hop answers
Use Microsoft GraphRAG to build community-structured knowledge graphs with hierarchical summaries, enabling agents to traverse relational context across document clusters rather than isolated chunks
Journey Context:
Naive RAG retrieves semantically similar chunks that lack relational context, failing on questions requiring synthesis \('How do the themes in Chapter 1 relate to Chapter 5?'\). GraphRAG indexes entities and relationships into Leiden communities, generating hierarchical summaries \(community reports\) that capture global document structure. Agents query this graph to retrieve connected subgraphs \(multi-hop relationships\) and community summaries, enabling complex reasoning that isolated vector chunks cannot support.
