我需要在我的网站中集成里程/距离搜索,我正在使用MongoDB地理空间索引,但是,我得到一些并且无法解决.下面是我正在使用的架构和命令......

=> db.properties.findOne({},{address:1})
{
    "_id" : ObjectId("585b909c870d907845b695fd"),
    "address" : {
        "postcode" : "W1D 1NN",
        "address1" : "Essence",
        "address2" : "United Kingdom House",
        "county" : "London",
        "town" : "LONDON",
        "latitude" : "51.5160229933117",
        "longitude" : "-0.139088472429092",
        "house_number" : "114",
        "location" : {
            "type" : "Point",
            "coordinates" : [
                -0.139088472429092,
                51.5160229933117
            ]
        }
    }
}

以下是我的索引......

=> db.properties.getIndexes()
[
    {
        "v" : 1,
        "key" : {
            "_id" : 1
        },
        "name" : "_id_",
        "ns" : "cherrydoorsync.properties"
    },
    {
        "v" : 1,
        "key" : …
