根据另一个子文档的字段子集查询子文档

Question

说我有三个模式

var Schema1 = new Schema({
    field1: {type: String},
    field2: {type: String},
    subdocument: {type: SubDocumentSchema, ref: 'SubDocument'}
})

var Schema2 = new Schema({
    field3: {type: String},
    field4: {type: String},
    subdocuments: {type: [SubDocumentSchema]}
})

var SubDocumentSchema = new Schema({
    excludedField: {type: String},
    field5: {type: String},
    field6: {type: String},
})

现在让我们说我有一个名为objSchema1的Schema1类型的对象：

{
    field1: "x",
    field2: "y",
    subdocuments: [
        {
            excludedField: "thisFieldIsntTested",
            field5: "equalField",
            field6: "equal"
        },
        {
            excludedField: "thisFieldIsntTested",
            field5: "nopeNotEqual",
            field6: "equal"
        },        
    ]
}

以及Schema2集合中某处的Schema2类型的文档：

{
    field3: "a",
    field4: "b",
    subdocuments: [
        {
            excludedField: "thisFieldIsntTested",
            field5: "equalField",
            field6: "equal"
        },
        {
            excludedField: "thisFieldIsntTested",
            field5: "notEqualThisTime",
            field6: "equal"
        },        
    ]
}

我将如何执行如下查询：查找集合Schema2中的所有文档，其中每个子文档都等于obj1中的相应子文档（不包括excludedField）？
