Mongoose using populate with an array of id's

Question

Is there any way to use populate in order to get just the documents with the id's specified in an array?

For example, this is how it works right now

Collection.findOne({element: elementId})
.populate({
  path: references
})
.exec((err, run) => {
  ....
});

And I'm searching for something like:

Collection.findOne({element: elementId})
.populate({
  path: {references: {_id: ["5ae9b6ac268d162b15747340", "5ae9b6ac268d162b15747341"]}}
})
.exec((err, run) => {
  ....
});

use $in and match in populate query

Collection.findOne({element: elementId})
.populate({
  path: 'references',
  match: {
    _id: {
      $in: ["5ae9b6ac268d162b15747340", "5ae9b6ac268d162b15747341"]
    }
  }
})

Yes, you would need to first declare it in your mongoose schema so it knows where to populate the data from. Please refer to : http://mongoosejs.com/docs/populate.html
