[frontier] Naive vector RAG returns noisy chunks that miss multi-hop relationships in my domain

Move to agentic GraphRAG: build a knowledge graph over your corpus, retrieve relevant entities and triplets, then use the co-occurrence of a chunk and a triplet as a high-confidence relevance filter before sending context to the LLM.

Journey Context:
Chunk-only RAG struggles with subtle clues and multi-hop associations because related facts are split across chunks and semantic similarity is a weak signal for structured reasoning. GraphRAG indexes entities and relations, giving precise factual anchors, but pure graph triplets can lack contextual grounding. The winning hybrid, shown in TeaRAG and GraphSearch, is to run semantic chunk retrieval and graph retrieval in parallel and up-rank chunks whose source material also appears in the retrieved triplets. This co-occurrence signal reconciles accuracy and token efficiency. The pattern is especially strong in medical, legal, and technical domains where explainable citations matter; simple FAQs do not need it.
