My mapping looks as below:

```
{
    "abc_history": {
        "mappings": {
            "abc-data-type": {
                "sData.Name": {
                    "full_name": "sData.Name",
                    "mapping": {
                        "Name": {
                            "type": "text",
                            "fields": {
                                "keyword": {
                                    "type": "keyword",
                                    "ignore_above": 256
                                }
                            }
                        }
                    }
                }
            }
        }
    }
}

```

I am trying to perform a wildcard search on `sData.Name` and used following query:

```
{
  "from": 0, 
  "size": 20, 
        "query": {
          "bool": {
            "must":[
              {"range": {"requestDate": { "gte": "2019-10-01T08:00:00.000Z" }}},
              {
                "wildcard": {
                  "sData.Name": "*Scream*"
                }
              }
            ]
          }
        },
        "sort": [
          { "requestDate": {"order": "desc"}}
        ]
}

```

The above query is returning empty response.  
How should I modify my query so that I can perform `wildcard search` on `sData.Name`

Maybe try to search for `*scream*` instead.

Side note: don't do wildcard searches like this unless you don't care about the speed. As the doc says, it's slow.
