Elasticsearch query based on timestamp

Question

This is my elasticsearch query that intends to filter data between 11 pm and 12 pm on the day 2015.08.04. But it doesn't filter and gives many errors.

"query" : {"range" :
            {"@timestamp" :
              {"gt" : "2015-08-04  11:00:00", "lt" : "2015-08-04 12:00:00"} 
            } 
          }  

Answer 1

It works with the following query

{
   "query":{
      "range":{
         "@timestamp":{
            "gte":"2015-08-04T11:00:00",
            "lt":"2015-08-04T12:00:00"
         }
      }
   }
}
