What is Elasticsearch fuzzy search?

A fuzzy search is done by means of a fuzzy matching query, which returns a list of results based on likely relevance even though search argument words and spellings may not exactly match. Exact and highly relevant matches appear near the top of the list. For this post, we will be using hosted Elasticsearch on Qbox.io.

What is fuzzy matching ElasticSearch?

Fuzzy queryedit. Returns documents that contain terms similar to the search term, as measured by a Levenshtein edit distance. An edit distance is the number of one-character changes needed to turn one term into another. These changes can include: Changing a character (box → fox)

What’s the default distance for a fuzzy search?

The default distance of an edit is 2. A value of ~0 signifies no expansion (only the exact term is considered a match), but you could specify ~1 for one degree of difference, or one edit. A fuzzy query can expand a term up to 50 additional permutations.

How does fuzzy search work in Microsoft Docs?

When to use hit highlighting in fuzzy search?

When results are ambiguous, hit highlighting can help you identify the match in the response. The use of hit highlighting to identify fuzzy matches has limitations and only works for basic fuzzy search.
