我可以在mongoose.js中为数组属性定义文档架构上的索引吗

Question

I have the following Document Schema in mongoose2.4.8 running on node0.4.12:

var UserSchema = new Schema({
  following: [{type: ObjectId, ref: 'User'}],
  followers: [{type: ObjectId, ref: 'User'}]
});

I want to speed up the lookup in the these arrays. Can i use mongoose.js index functionality? And how?

Answer 1

Are you trying to lookup the ObjectId in the arrays? Or are you looking for the User? If the latter, add the index on the User Schema.
