Arrays 从mongodb gte搜索隐藏子数组不匹配

因此，我能够让我的

gte

查询为mongodb工作。但是，我注意到查询whileyes正确地打印出文档。它不会删除/隐藏不正确的子阵列

例如：

{history:[{starttime:1593143279079},{starttime:1593236606706}}

现在我只想要gte到1593236606706的子阵列

但是，当我运行以下查询时

{"history.starttime":{$gte:1593236606706}}

我得到了正确的文档，因为是的文档有一个gte，然后是1593236606706，但是我也看到了所有没有相关的子数组，比如1593143279079

现在我知道我可以做foreach签入节点或任何其他程序。但是，在文件返回之前，是否有必要删除或隐藏不相关的文件

下面是示例数据

您需要筛选数组

{
    $project:{
        "history":{
            $filter:{
                input:"$history",
                cond:
                    {$gte:["$$this.starttime",1593236606706]}               
            }
        }
    }
}

工作

您可以使用位置投影运算符$仅检索匹配的数组元素。请提供一个示例@文档中有一些例子。我试过你的代码，它给了我这个错误

必须是一个像“[{id:1}，{{id:2}]”这样的文档数组。

我已经添加了我们的示例数据，但我还要看看是否可以对您的代码进行一些修改以使其正常工作。我可以理解您的答案的意思。我根据您提供的内容给出了答案，并且工作正常。最好修改问题以更新数据结构。我已经更新了问题。对不起，我以为我说得够清楚了。我的错。很抱歉，我的浏览器没有发布更新-现在我没有收到任何错误，您提供的数据
