Searching with runtime, without mapping with runtime

hello , I am trying to learn runtime .
it uses in the script the painless language , It wold be nice to I understand this language , that I could test it before mapping .
the way to test it before mapping it is search with runtime .
here it has one example -


PUT my-index-000002-test/
{
  "mappings": {
    "runtime": {
      "day_of_week": {
        "type": "keyword",
        "script": {
          "source": "emit(doc['@timestamp'].value.dayOfWeekEnum.getDisplayName(TextStyle.FULL, Locale.ROOT))"
        }
      }
    },
    "properties": {
      "@timestamp": {"type": "date"}
    }
  }
}

GET my-index-000002-test/_mapping


POST my-index-000002-test/_bulk?refresh=true
{"index":{}}
{"@timestamp":1516729294000,"model_number":"QVKC92Q","measures":{"voltage":"5.2","start": "300","end":"8675309"}}
{"index":{}}
{"@timestamp":1516642894000,"model_number":"QVKC92Q","measures":{"voltage":"5.8","start": "300","end":"8675309"}}
{"index":{}}
{"@timestamp":1516556494000,"model_number":"QVKC92Q","measures":{"voltage":"5.1","start": "300","end":"8675309"}}
{"index":{}}
{"@timestamp":1516470094000,"model_number":"QVKC92Q","measures":{"voltage":"5.6","start": "300","end":"8675309"}}
{"index":{}}
{"@timestamp":1516383694000,"model_number":"HG537PU","measures":{"voltage":"4.2","start": "400","end":"8625309"}}
{"index":{}}
{"@timestamp":1516297294000,"model_number":"HG537PU","measures":{"voltage":"4.0","start": "400","end":"8625309"}}



GET my-index-000002-test/_search
{
  "query": {
    "match_all": {}
  },
   "fields" : ["day_of_week"]
}

this worked for me .
it returns -

"hits": [
      {
        "_index": "my-index-000002-test",
        "_id": "pEH4q4kB6LNnmdzdEkwe",
        "_score": 1,
        "_source": {
          "@timestamp": 1516729294000,
          "model_number": "QVKC92Q",
          "measures": {
            "voltage": "5.2",
            "start": "300",
            "end": "8675309"
          }
        },
        "fields": {
          "day_of_week": [
            "Tuesday"
          ]
        }
      },
      {
        "_index": "my-index-000002-test",
        "_id": "pUH4q4kB6LNnmdzdEkwe",
        "_score": 1,
        "_source": {
          "@timestamp": 1516642894000,
          "model_number": "QVKC92Q",
          "measures": {
            "voltage": "5.8",
            "start": "300",
            "end": "8675309"
          }
        },
        "fields": {
          "day_of_week": [
            "Monday"
          ]
        }
      },

NOW, I am trying to search with runtime , without mapping with runtime .
this is important to I test the Painless Script .
So , I did like that -

GET my-index-000002-test/_search
{
  "runtime_mappings": {
    "day_of_week": {
      "type": "keyword",
      "source": "emit(doc['@timestamp'].value.dayOfWeekEnum.getDisplayName(TextStyle.FULL, Locale.ROOT))"
    }
  },
  "query": {
     "match_all": {}
  },
  "fields" : ["day_of_week"]
}

It is the same script that I used to mapping , and after search .
but it gave me this error -

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "unknown parameter [source] on runtime field [day_of_week] of type [keyword]"
      }
    ],
    "type": "search_phase_execution_exception",
    "reason": "all shards failed",
    "phase": "query",
    "grouped": true,
    "failed_shards": [
      {
        "shard": 0,
        "index": "my-index-000002-test",
        "node": "d8DCCAzDQGCLFPA7rX5QSQ",
        "reason": {
          "type": "mapper_parsing_exception",
          "reason": "unknown parameter [source] on runtime field [day_of_week] of type [keyword]"
        }
      }
    ]
  },
  "status": 400
}

It is not, in the mapping you used:

      "day_of_week": {
        "type": "keyword",
        "script": {
          "source": "emit(doc['@timestamp'].value.dayOfWeekEnum.getDisplayName(TextStyle.FULL, Locale.ROOT))"
        }
      }

But in your search you used:

    "day_of_week": {
      "type": "keyword",
      "source": "emit(doc['@timestamp'].value.dayOfWeekEnum.getDisplayName(TextStyle.FULL, Locale.ROOT))"
    }
  }

Which is the issue, the source needs to be inside the script object as you can see in the documentation.

thanks, it works
