查詢具有地理空間索引和字段的Mongodb集合

我有一個具有座標的位置字段的mongodb集合。在進行過濾器搜索時，我希望獲取範圍內的文檔和特定名稱，我的例子是storeName。在這方面有什麼幫助？以下是我的收藏。查詢具有地理空間索引和字段的Mongodb集合

    "website" : "http://www.homedepot.com/l/San-Jose-ge/CA/San-Jose/95125/1861" 
    }

這是目前爲止的查詢。

db.storelist.find({ location: { $nearSphere: { $geometry: { type: "Point", coordinates: [ -121.8683031,37.3029936 ] }, $maxDistance: 2000 } } })

我得到距離內的文件列表，但無法理清我放置其他字段的位置，即storeName。

在這方面的任何幫助將不勝感激。提前致謝。

您可以添加額外的查詢{...}像這裏面：

db.storelist.find({ 
    "storeName": "The Home Depot", 
    location: { 
    $nearSphere: { 
     $geometry: { 
     type: "Point", 
     coordinates: [-121.8683031, 37.3029936] 
     }, 
     $maxDistance: 2000 
    } 
    } 
})
