QUEST: Query Optimization in Unstructured Document Analysis

Summary: QUEST: LLM-aware query optimizer for unstructured documents using index + evidence-augmented retrieval and per-document (instance-optimized) plans to minimize costly extraction invocations. Adds LLM-cost-aware operator ordering and join→filter execution, yielding 30%–6× cost savings and 10%–27% F1 gains. (summarized by gpt-5-mini on Feb 09 2026)
