elasticsearch脚本字段与_source一起

Question

关于脚本字段the official documentation后，我构建了类似这样的查询

GET /abc/dfg/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "bool": {
            "should": [
              {
                "range": {
                  "object.property": {
                    "gte": 6.05,
                    "lte": 18.15,
                    "include_lower": false,
                    "include_upper": false
                  }
                }
              }
            ]
          }
        }
      ],
      "filter": [
        {
          "bool": {
            "must": [
              {
                "geo_distance": {
                  "distance": "25mi",
                  "object.geo_point_property": {
                    "lat": 40.753333,
                    "lon": -73.976667
                  }
                }
              }
            ]
          }
        }
      ]
    }
  },
  "script_fields": {
    "distance": {
      "script": {
        "inline": "doc['object.geo_point_property'].planeDistanceWithDefault(params.lat,params.lon, 0)",
        "params": {
          "lat": 40.753333,
          "lon": -73.976667
        },
        "lang": "painless"
      }
    }
  }
} 

我在点击中获得了距离脚本字段，但丢失了文档中的所有_source字段。

"hits": [
  {
    "_index": "abc",
    "_type": "dfg",
    "_id": "123456789",
    "_score": 5.431662,
    "fields": {
      "distance": [
        452.7564081099714
      ]
    }
  },
]

有什么方法可以在文档的_source字段旁边获取脚本字段？

我寻找类似的东西：

"hits": [
  {
    "_index": "abc",
    "_type": "dfg",
    "_id": "123456789",
    "_score": 5.431662,
    "fields": {
      "distance": [
        452.7564081099714
      ]
      "object": {
        "property": 123,
        "geo_point_property": xyz
      }
    }
  },
]

PD：即时使用弹性5.1

只需在查询中添加_source: true

即可

POST /abc/dfg/_search
{
  "_source": true,         <--- add this
  "query": {
    "bool": {
      "must": [
      ...
