How to perform fuzzy matching on multiple fields in Spanish?

In Elasticsearch, you can use a Bool Query to perform fuzzy matching on multiple fields. Bool Query supports combining multiple conditions, including fuzzy matching, exact matching, range matching, etc.

Here is an example of using a Boolean query to perform fuzzy matching on multiple fields:

{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "field1": {
              "query": "keyword",
              "fuzziness": "AUTO"
            }
          }
        },
        {
          "match": {
            "field2": {
              "query": "keyword",
              "fuzziness": "AUTO"
            }
          }
        }
      ]
    }
  }
}

In the above example, field1 and field2 represent two fields for fuzzy matching, and keyword represents the keyword to be matched. The fuzziness parameter specifies the degree of fuzzy matching, with AUTO indicating the automatic calculation of the edit distance for fuzzy matching.

By adding multiple match clauses to the should array, it is possible to achieve fuzzy matching on multiple fields. The should field in a boolean query indicates that any one of the clauses matching successfully is sufficient. If all fields need to match successfully in order for it to be considered a successful match, the must field can be used.

Please note that, in order to perform fuzzy matching, the field type should be text, not keyword. If the field is of keyword type, you can convert it using a match query before querying.
