希望我能解释一下我的问题。

我正在使用Google的自动填充功能来获取目的地。一旦我有了目的地,我可以使用google的地方api来查找几何视口。但是视口是从北/东到南/西。我的问题是Elasticsearch geo_bbox从顶部/左侧到底部/右侧。见下面的例子。

Google Place API响应:

   "result" : {
      "address_components" : [

            "types" : [ "administrative_area_level_2", "political" ]
         },
         {

弹性搜索示例

{
    "filtered" : {
        "query" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_bounding_box" : {
                "pin.location" : {
                    "top_left" : {
                        "lat" : 40.73,
                        "lon" : -74.1
                    },
                    "bottom_right" : {
                        "lat" : 40.717,
                        "lon" : -73.99
                    }
                }
            }
        }
    }
}

是否有更好的方法可以从谷歌获取更多信息,或者可以从备用角落进行弹性搜索。虽然文档没有说明这一点?

哦,亲爱的,我有多厚。

我需要做的就是将结果换成弹性搜索。即,

{
    "filtered" : {
        "query" : {
            "match_all" : {}
        },
        "filter" : {
            "geo_bounding_box" : {
                "pin.location" : {
                    "top_left" : {
                        "lat" : result.northeast.lat,
                        "lon" : result.southwest.lon
                    },
                    "bottom_right" : {
                        "lat" : result.southwest.lat,
                        "lon" : result.northwest.lon
                    }
                }
            }
        }
    }
}

如果你知道东北角和西南角,你可以计算西北角(左上角)和东南角(右下角):

var NE = bounds.getNorthEast();
var SW = bounds.getSouthWest();

// calculated points
var NW = new google.maps.LatLng(NE.lat(), SW.lng());
var SE = new google.maps.LatLng(SW.lat(),NE.lng());
