I have the following query in dev tools in Kibana that works well for me, without determining a search time.
GET /example*/_count
{
  "query": {
    "query_string": {
      "query" : "(API002) AND (operation)"
                }
       }
}
Now I want to make this query within a specific time but I could not. I try this and with some modifications but it doesn't work for me.
GET /example*/_count
{
  "query": {
    "query_string": {
      "query" : "(API002) AND (operation)"
           },
              "range" : {
                "gte": "2019-09-16 00:00:00", 
                "lte": "now", 
                "time_zone": "+01:00"
                        }
          }
}
