An Incrementally Maintainable Index for Approximate Lookups in Hierarchical Data
Summary: Persistent, incrementally maintainable index for approximate lookups in hierarchical data with pq-grams. Updates driven by a log of tree edits; only a small pq-gram set is refreshed, with correctness proven and scalable results on synthetic data. (summarized by gpt-5-nano on Feb 09 2026)
