Efficient and Effective KNN Sequence Search with Approximate n-grams

Summary: Proposes KNN sequence search under edit distance using longer approximate n-grams for pruning with a two-level index. CA-based filtering with a frequency queue reduces false positives, enabling progressive results and early termination; parallel execution scales. (summarized by gpt-5-nano on Feb 09 2026)
