What is ElasticSearch fuzzy search?

Answer»

With fuzzy search, you can FIND DOCUMENTS with terms similar to your search term based on a Levenshtein edit distance measure. Edit distance is essentially the number of single-character changes or edits required to change one term into another. Among these changes are:

  • Change one character (box → fox)
  • Remove one character (black → lack)
  • Insert one character (sic → sick)
  • Transpose two adjacent characters (act → cat)

Within a SPECIFIC edit distance, the fuzzy query generates a list of all POSSIBLE variations and expansions of the search term. After that, the query returns a list of all possible matches. The most relevant and exact matches APPEAR near the top of the list.
