An Efficient and Versatile Query Engine for TopX Search

Summary: TopX adapts threshold algorithms to ranked XML retrieval, aggregating element scores at document level while combining vague content and path predicates. Its index-aware scheduling postpones costly structural checks and supports probabilistic approximate top-k with controllable precision loss. (summarized by gpt-5.6-luna on Jul 24 2026)
