I want to search by calculated field.

For example, I calculate field by script & want to call it in query after, like in example below.

POST /process-instance/_search
{
  "script_fields": {
    "duration": {
      "script": {
        "source": 
          """
            doc['completedAt'].value.toInstant().toEpochMilli() - doc['createdAt'].value.toInstant  ().toEpochMilli()
          """,
        "lang": "painless"
      }
    }
  },
  "query": {
    "range": {
      //using calculated field 'duration' in search query
      "duration": {
        "gte": 1000
      }
    }
  }
}

Field ‘duration’ calculates and returns in result for every document, but when I use it in search querty, result is empty.

Have you any idea, how to use calculated field in search query?
