Report #14474
[architecture] Single-hop vector search fails to connect related facts across time
Use graph-based memory \(knowledge graph\) alongside vector storage, and implement multi-hop retrieval queries \(e.g., Cypher queries or structured traversals\) to connect entities across disparate memories.
Journey Context:
Vector DBs excel at semantic similarity but fail at relational reasoning. If a user mentions 'Alice' in session 1 and 'Bob is Alice's brother' in session 5, a vector search for 'Alice's brother' might miss Bob if the embeddings aren't close enough. Graph memory captures the edges, allowing the agent to traverse from Alice to Bob, solving multi-hop reasoning gaps.
