Not getting proper result while searching special characters in query string

This is my query

GET /momsarchival1/_search
{
  "track_total_hits": true,
  "query": {
    "bool": {
      "must": [
        {
          "bool": {
            "must": [
              {
                "query_string": {
                  "default_field": 
                    "GECORRIGEERDETOEVOEGING.keyword",
                  "query": "*(a-n)*",
                  "analyze_wildcard": "true",
                  "default_operator": "AND"
               
                }
              }
            ]
          }
        }
      ]
    }
  },
  "_source": ["GECORRIGEERDETOEVOEGING"], 
  "size": 30,
  "from": 0,
  "sort": [
    {
      "ORDERNUMMER.keyword": {
        "order": "asc"
      }
    }
  ]
}
