Report #29750

[frontier] Vector RAG fails on queries requiring implicit relationship traversal across chunks

Index documents into knowledge graphs with community detection and perform global\+local search via GraphRAG

Journey Context:
Similarity search misses 'friend of a friend' connections critical for multi-hop reasoning. GraphRAG extracts entities and relationships, then applies community detection to identify semantic clusters. The query pipeline combines global search \(community summaries\) for abstract questions and local search \(entity neighborhoods\) for specific facts. Microsoft GraphRAG implementations show 70% improvement on complex reasoning benchmarks compared to naive RAG.
