Report #5207
[architecture] Relying solely on vector similarity search for multi-hop deductive retrieval
Augment vector memory with a knowledge graph \(GraphRAG\) or implement iterative retrieval loops where the output of one retrieval informs the next query.
Journey Context:
Vector stores excel at finding semantically similar single facts but fail when answering a question requires connecting two disparate facts \(e.g., 'Which library does the author of the tool I installed yesterday prefer?'\). The embedding for the question won't match the embedding for the specific library. A graph structure allows traversal from the tool -> author -> preference, or an iterative loop allows the agent to first retrieve the author, then query their preference.
