Dears ,

am new to elastic community , i need your help to to write elastic query  
i have many documents created through logstash and i want to get the result were the documents have same result in different field ,

```auto
"filter": {
    "script": {
      "script": "doc['field1'].value == doc['field2'].value "
    }
  }
 }

```

i tried to filter out the result using above query but am getting " no field found for 'field2' in mapping with types "
