比如我们有很多的4S店,然后给了用户一个APP,在某个地方的时候,可以根据当前的地理位置搜索一下,自己附近的4S店

PUT /car_shop_location
{
  "settings": {
    "number_of_shards": 3,
    "number_of_replicas": 0
  },
  "mappings": {
    "shops": {
      "properties": {
        "pin": {
          "properties": {
            "location": {
              "type": "geo_point"
            }
          }
        }
      }
    }
  }
}

PUT car_shop_location/shops/1
{
  "name": "深圳宝马4S店",
  "pin": {
    "location": {
      "lat": 40.12,
      "lon": -71.34
    }
  }
}

1、搜索两个坐标点组成的一个区域
2、指定一个区域,由三个坐标点组成
3、搜索距离当前位置在200km内的4S店
