Hi,
I have the following query.
GET /logstash-win*/_search
{
  "query": {
    "bool": {
      "must": [
        { "regexp": { "event_data.CommandLine": ".*Hidden.*" }}
      ],
      "filter": [
        { "range": { "@timestamp": {"from": "now-1d", "to": "now" }}}
      ]
    }
  }
}
There exists a Document in my defined time interval with a field 'event_data.CommandLine' wich includes the word 'Hidden'. The Field is from type 'text'.
There exosts also another Dodument with that field with a File Path included like 'ANY.dll'. It will be find by the following regexp.
.*dll.*"
Whats the problem here?
I am using Elasticsearch 5.4 with XPack
Thanks
David
