An Efficient Index Structure for String Databases
Summary: Substrings mapped to an integer space by wavelet coefficients for scalable, on-disk substring search. MBR-based indexing with a lower-bound edit-distance proxy enables NN and range pruning, yielding 50–95% pruning and substantial I/O/CPU savings. (summarized by gpt-5-nano on Feb 09 2026)
