Notes

Fuzzy search uses an ensemble of Jaro-Winkler, n-gram, Damerau-Levenshtein, and jurisdiction-aware phonetic algorithms. Results include a similarityScore (0-1).
Name search returns substring matches — searching “APPLE” also returns “PINEAPPLE”.
Owner search ranks exact and prefix matches above substring matches.
Multi-jurisdiction queries interleave results round-robin so no single jurisdiction dominates when results are truncated.
When no results are found, a suggestion field provides actionable guidance.
