Plugins Distance Operators - CefasDB Docs

Documentation excerpt

Distance plugins return a scalar where smaller means closer. This lets every operator fit the same predicate shape:

Use edit distance for strings where typos matter. Use Jaro-Winkler for names. Use Jaccard for sets. Use cosine for normalized embeddings. Use Haversine for latitude and longitude.

At scale, pair distance operators with an index plugin. A trigram index can narrow candidates before Levenshtein. Vector LSH can narrow candidates before cosine. Geohash can narrow candidates before Haversine.
