将脚本与ScriptedMetricAggregationBuilder elasticsearch一起使用时，如何访问记录内的对象？

Question

"recordOne": {
  "properties": {
    "id": {
      "type": "integer"
    },
    "recordtwo": {
      "properties": {
        "propertyone": {
          "type": "integer"
        },
        "propertytwo":{
          "type":"date"
        }
      }
    }
  },
  "_parent": {
    "type": "parentrecord"
  }
}

Here i am trying to access recordtwo properties like "doc.recordtwo.propertyone"

i am getting this exception :

'Elasticsearch exception [type=illegal_argument_exception, reason=No field found for [recordtwo] in mapping with types [recordOne]]'

Though i am able to access id. ie

"doc.id"

Answer 1

我在下面尝试过，并且有效。

"doc['recordtwo.propertyone']"
