聚合在两个嵌套的ID数组上

Question

对于聚合查询，我需要您的帮助。 发布前我进行了一些搜索，但是没有找到结果对我有用。

我有那些文件：

订单：

{
    "_id" : MongoId,
    "customId" : integer,
    ... other fields
    "circuit" : MongoId, // Ref to Circuit Document
    "agency" : MongoId, // Ref to Agency document
    "customer" : MongoId, // Ref to Customer document
    "places" : [ // Array of MongoId ref to place document
        MongoId, 
        MongoId,
        ...
    ],
    "materials" : [ // Array of MongoId ref to material document
        MongoId, 
        MongoId,
        ...
    ],
    ... other fields
}

电路：

{
    "_id" : MongoId,
    "customId" : Integer,
    "name" : String,
    "state" : String,
    "type" : String,
    "agency" : MongoId,
    "trucks" : [ // Array of MongoId ref to truck document
        MongoId, 
        MongoId,
        ...
    ],
    "drivers" : [ // Array of MongoId ref to truck document
        MongoId, 
        MongoId,
        ...
    ],
    "orders" : [ // Array of MongoId ref to order document
        MongoId, 
        MongoId,
        ...
    ]
}

所以我需要为每个赛道获得司机，卡车和订单。这部分没问题，查询有效（请参见下文）。

但是我没有从每个电路的每个订单中获得所有的位置和材料。

所以，这是我当前的查询：

db.circuit.aggregate([
    {$match: {"date": {$lte: ISODate("2019-04-01 23:59:59")}}},
    {$match: {"date": {$gte: ISODate("2019-03-31 00:00:59")}}},
    {
        $lookup: {
            from: "agency",
            localField: "agency",
            foreignField: "_id",
            as: "agency"
        }
    },
    {$unwind: "$agency"},
    {
        $lookup: {
            from: "order",
            localField: "orders",
            foreignField: "_id",
            as: "orders"
        }
    },
    {
        $lookup: {
            from: "driver",
            localField: "drivers",
            foreignField: "_id",
            as: "drivers"
        }
    },
    {
        $group: 
        {
            "_id": "$_id",
            "agency": {$addToSet: "$agency.name"},
            "date": {$addToSet: "$date"},
            "orders": {$addToSet: "$orders"},
            "drivers": {$addToSet: "$drivers"},
        }
    },
    {$unwind: "$agency"},
    {$unwind: "$date"},
    {$unwind: "$orders"},
    {$unwind: "$drivers"},
    {
        $project: {

                                ]

                                ]
                            }

我尝试了几种徒劳地从电路（两层嵌套文档）的订单中获取位置和材料的方法。

为了说明我的需求，输出必须查看此内容：

{
    "_id" : "5c6e6f7be05bd900a1682582",
    "customId" : 4966075,

您能否帮助我为查询实现最后一部分，并且如果可能的话，还可以提供良好的性能：）

谢谢！
