Indexing for Keyword Search with Structured Constraints
Summary: Presents index designs with provable, often near‑optimal guarantees (under standard hardness conjectures) for keyword search combined with structured constraints (range, linear predicates, spatial prioritization). Closes a theory gap where prior solutions were mainly heuristic or naive scans. (summarized by gpt-5-mini on Feb 09 2026)
