从 mongodb gte 搜索中隐藏不匹配的子数组

Question

所以我已经能够让我的 gte 查询为 mongodb 工作。但是我注意到查询 while yes 正确打印出文档。它不会 remove/hide 不正确的子数组。

例如：

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

现在我只想要 gte 到 1593236606706 的子数组

然而当我运行下面的查询

{"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不相关的子数组，比如 1593143279079。

现在我知道我可以在节点或任何其他程序中执行 foreach 签入。但肯定有办法删除或隐藏它之前的不相关文件returns?

这是示例数据

Answer 1

您需要过滤数组。

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