elasticsearch - 如何在 elsaticsearch 中为具有 lat lon 和 alt 的地理点编写映射？

Question

My_Json_File

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

• 请就如何在地理点和 “_id”字段中遇到这个“alt”字段提供建议，并为上述 JSON 文件编写合适的映射。

在您的位置上，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。

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
    },
} 

和映射应该看起来像：

  "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 类型字段接收如下数据：

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