Researchers have introduced Q+, a set of structured query and evidence processing tools that improve web search for AI research agents by making search behavior more deliberate and traceable. Integrated into Eigent, an open-source multi-agent system for computer use, Q+ guides query planning, monitors search progress, and extracts evidence from long web documents. Testing across four benchmarks shows accuracy improvements of 0.6 to 3.8 percentage points depending on the model backend, with case studies indicating more coherent tool-calling trajectories and explicit evidence handling.
