Question

我正在尝试按公里数排序我的字段类型是 "location": { "properties": { "lat": { "type": "float" }, "lon": { "type": "float" } } },

在我的索引中，其存储类似"location": { "lon": 72.9814762, "lat": 33.7013063 },

和查询中

Answer 1

@apokryfos是正确的，您必须将数据映射为地理位置。之后，您就可以对_geo_distance进行排序

"sort": [
    {
      "_geo_distance": {
        "coords": {
          "lat": -27.87,
          "lon": -54.43
        },
        "order": "asc",
        "unit": "km",
        "mode": "min",
        "distance_type": "arc",
        "ignore_unmapped": true
      }
    }
  ]

Answer 2

您必须手动进行映射。请在下面找到映射示例（适用于ES 7.4.0）。第一个命令创建索引，第二个命令映射2个字段（一个类型为geo_point的字段），第三个命令检索映射信息。
