Architectural patterns for graph-enhanced RAG
Learn how to fix RAG hallucinations by combining vector search with graph-based structural context.
30-Second TL;DR
What Changed
Vector-only RAG fails in enterprise domains because it discards data topology and structural relationships.
Why It Matters
Adopting a Graph RAG pattern significantly reduces hallucinations in complex enterprise use cases like supply chain management. It allows LLMs to perform multi-hop reasoning that is otherwise impossible with flat vector embeddings.
What To Do Next
Evaluate your current RAG pipeline for multi-hop reasoning failures and consider integrating a graph database like Neo4j to store explicit entity relationships.
Key Points
- •Vector-only RAG fails in enterprise domains because it discards data topology and structural relationships.
- •Graph-enhanced RAG combines semantic vector search with structural determinism from graph databases.
- •Structure must be enforced during the ingestion phase using entity and relationship extraction.
- •Hybrid retrieval prevents hallucinations by providing the LLM with explicit context links for multi-hop reasoning.
