GET filebeat-*/_search
{
  "query": {
      "bool": {
        "must": [
        {
           "query_string": {
            "analyze_wildcard": true,
             "query": "message:(\"Exception\")",
      "fuzzy_max_expansions": 50
         }
       
           },
       {
                  "range": {
                    "@timestamp": {
                      "gte": "now-2h",
                      "lte": "now",
                      "format": "epoch_millis"
                    }
                  }
                }
       ]
     }
   }
}

                }
       ]
     }
   }
}
