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.Apr 6, 2017
What does the term fuzzy matching mean?

What is Elasticsearch matching?
The match query analyzes any provided text before performing a search. This means the match query can search text fields for analyzed tokens rather than an exact term.
What is fuzziness in Elasticsearch?
In Elasticsearch, fuzzy query means the terms in the queries don't have to be the exact match with the terms in the Inverted Index. To calculate the distance between query, Elasticsearch uses Levenshtein Distance Algorithm.Dec 6, 2020
Does Elasticsearch do fuzzy matching?
In Elasticsearch, fuzzy query means the terms are not the exact matches of the index. The result is 2, but you can use fuzziness to find the correct word for a typo in Elasticsearch's fuzzy in Match Query. For 6 characters, the Elasticsearch by default will allow 2 edit distance.Dec 6, 2020
What is lenient in Elasticsearch?
lenient. (Optional, Boolean) If true , format-based errors, such as providing a text value for a numeric field, are ignored. Defaults to false . max_determinized_states.
What is query match?
The match query is of type boolean . It means that the text provided is analyzed and the analysis process constructs a boolean query from the provided text. The lenient parameter can be set to true to ignore exceptions caused by data-type mismatches, such as trying to query a numeric field with a text query string.
What is minimum should match Elasticsearch?
Minimum Should Match is another search technique that allows you to conduct a more controlled search on related or co-occurring topics by specifying the number of search terms or phrases in the query that should occur within the records returned.
