问题描述

My_Json_File

{
"addressInfo": {
    "city": "Wimsheim",
    "postcode": "71299",

  推荐答案

  在你的位置，我会将alt移出地理点，并使用映射类型geo_point，它为地理点字段的进一步操作提供了许多其他选项。

  On your place I would move "alt" out of geopoint and use mapping type "geo_point" which provides a lot of other options for further operations on geopoint field.

  它看起来像：

  {
      "_id": "ac169008-aa5b-4b09-aa9e-3bf3018f316d"
      "addressInfo": {
          "city": "Wimsheim",
          "postcode": "71299",
          "geopoint": {
              "lon": 48.845877,
              "lat": 8.821861,
          },
          "alt": 0.0
      },
  } 
  

  ，映射应如下所示：

    "properties": {
      "_id": {
        "type": "string"
      },
      "addressInfo": {
        "type": "nested",
        "properties": {
          "city": {
            "type": "string",
          },
          "postcode": {
            "type": "integer",
          },
          "alt": {
            "type": "float",
          },
          "geopoint": {
            "type": "geo_point",
          },
        },
      },
    },
  

  其中geo_point类型字段接收数据，如：

  where geo_point type field receives data like:

  {"lat": 8.821861, "lon": 48.845877}
