Report #76244

[architecture] Vector similarity search fails on multi-hop reasoning questions

Use an agent loop for retrieval \(e.g., ReAct\) or graph-based memory \(Knowledge Graph\) instead of single-shot vector search.

Journey Context:
If the query is 'What library did the lead developer of project X recommend?', a single vector search will fail because the connection between 'project X', 'lead developer', and 'library' is spread across different documents. You need iterative retrieval \(search project X -> find lead dev -> search lead dev's recommendations\) or a graph where these edges are explicitly stored to bridge the semantic gap.
