Mongodb日期范围查询返回无结果

Question

我对MongoChef中的下列查询没有任何兴趣 - 它不返回任何结果。如果我在mLab中运行相同的查询，那么它可以工作。我想知道它有什么问题。

$match : { 
"account_balances_date": { 
    "$gte": { 
     "$date": "2016-04-01T00:00:00.000Z" 
    }, 
    "$lte": { 
     "$date": "2016-08-01T00:00:00.000Z" 
    } 
} 
} 

下面是查询范围内的account_balances_date示例文档。感谢

如上所述here，操作者$date是扩展JSON格式存储date对象。在运行查询时，所有GUI工具可能都无法识别。相反，你可能想用ISODate("2016-04-01T00:00:00.000Z")来代替：

$match: { 
    "account_balances_date": { 
     "$gte": ISODate("2016-04-01T00:00:00.000Z"), 
     "$lte": ISODate("2016-08-01T00:00:00.000Z") 
    } 
}
