Demo environments are controlled. The inputs are predictable, the tools work reliably, and the task was chosen because the system handles it well. Real tasks have ambiguous inputs, tools that return …
Hybrid search combines dense vector retrieval with sparse keyword retrieval to get the best of both approaches. In theory, it should outperform either method alone. In practice, it still misses …
