使用相同字段成功搜索后，MongoDB（Mongoose / MLab）中的数据丢失

I have a very specific question. I have a web project that is using Express (Node.JS) and MLab (MongoDB/Mongoose). I've manually edited several records in a collection (yeah, I know, bad idea) and am using one of those fields in a Mongoose search. The schema is defined as follows: (relevant part only)

我有一个非常具体的问题。我有一个使用Express（Node.JS）和MLab（MongoDB / Mongoose）的Web项目。我已经手动编辑了一个集合中的几个记录（是的，我知道，坏主意）并且正在使用Mongoose搜索中的其中一个字段。模式定义如下:(仅限相关部分）

user: {
        id: {
            type: mongoose.Schema.Types.ObjectId,
            ref: "Registration"
        },
        username: String,
        type: String
    }

My search is as follows:

我的搜索如下：

Master.find({$or: [{'user.type': 'committee'}, {'user.type': 'admin'}]}, function(err, foundUsers) {
    do stuff
});

The search works just fine (using 'user.type'), but the user object in each record is undefined in foundUsers.

搜索工作正常（使用'user.type'），但是在FoundUsers中未定义每个记录中的用户对象。

What am I missing? Thanks!

我错过了什么？谢谢！

Found it. I tried to pull a fast one and add something to the user record that wasn't in the Registration Schema. Mongo was smarter than I was in this case.

找到了。我尝试拉一个快速的，并添加一些不在注册模式中的用户记录。在这种情况下，Mongo比我更聪明。
