Wildcard and Fuzzy query together in elastic search

问题

I am trying to design a query in which, I can use wildcard and Fuzzy query together.

According to me, query_string is used for wildcard searches and multi_match can be used for fuzziness.

I want a query which will search on words :-

"elast" : - provide results elastic and elasticsearch. "elasttc" :- also provide results as elastic and elasticsearch.

Elastic search supports wildcard and fuzzy query together??

Thanks in advance...

  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "title": "testing"
          }
        },
        {
          "wildcard": {
            "title": "*testing*"
          }
        },
        {
          "fuzzy": {
            "title": "testing"
          }
        }
      ],
      "minimum_should_match": 1
    }
  }
}

You can use it with Query String with wildcards. The suffix ~AUTO* enables a prefix query with fuzzy, also you can use the fields selection like multi_match query:

{
    "query": {
        "query_string" : {
            "fields" : ["name^2", "content^1"],
            "query" : "elasttc~AUTO*"
        }
    }
}

You can change the AUTO keyword with a numeric value too, as the same fuzziness parameter.
