            {
              "wildcard": { "title": "*"   search   "*" }
            }

CodePudding user response：

If you want to match only some of the word from query then you can use match query with operator set to or.

{
  "query": {
    "match": {
      "title": {
        "query": "i have issues",
        "operator": "or"
      }
    }
  }
}

Update

To run the query which you mentioned in comment, You can use match_bool_prefix query.

{
  "query": {
    "match_bool_prefix": {
      "title": {
        "query": "i have issu"
      }
    }
  }
}
