我刚刚开始与MongoDB在几天内，这里是我的收藏：

{
    PlayerUid:1
    ListData:
    [
        {
            Id:100
            ListInfo:[
                {
                    Uid:1,
                    content:"Those I don't care"
                },
                {
                    Uid:2,
                    content:"Those I don't care"
                },
                {
                    Uid:3,
                    content:"Those I don't care"
                },
                {
                    Uid:4,
                    content:"Those I don't care"
                }
            ]
        },
        {
            Id:101
            ListInfo:[
                {
                    Uid:5,
                    content:"Which I wanted"
                },
                {
                    Uid:6,
                    content:"Those I don't care"
                },
                {
                    Uid:7,
                    content:"Those I don't care"
                },
                {
                    Uid:8,
                    content:"Those I don't care"
                }
            ]
        }
    ]
},
{
    PlayerUid:2
    ListData:
    [
        {
            Id:100
            ListInfo:[
                {
                    Uid:9,
                    content:"Those I don't care"
                },
                {
                    Uid:10,
                    content:"Those I don't care"
                },
                {
                    Uid:11,
                    content:"Those I don't care"
                },
                {
                    Uid:12,
                    content:"Those I don't care"
                }
            ]
        },
        {
            Id:101
            ListInfo:[
                {
                    Uid:13,
                    content:"Those I don't care"
                },
                {
                    Uid:14,
                    content:"Those I don't care"
                },
                {
                    Uid:15,
                    content:"Those I don't care"
                },
                {
                    Uid:16,
                    content:"Those I don't care"
                }
            ]
        }
    ]
}

我想获取条件为PlayerUid = 1，Id：101，Uid = 5的数据。
我试过了

findOne({ PlayerUid: 1}, { ListData: { $elemMatch: { Id: 101 } } })

我得到了

{
  ListData: [ { Id: 101, ListInfo: [Array] } ]
}

然后我就被卡住了，我不知道如何在ListInfo中获取或归档数据。

{
    Uid:5,
    content:"Which I wanted"
}
or
{
    PlayerUid:1
    ListData:
    [
        {
            Id:100
            ListInfo:
            [
                {
                    Uid:5,
                    content:"Which I wanted"
                }
            ]
        }
    ]
}

可能吗？
