In Node with Mongoose I want to find an object in the collection Content. It has a list of sub-documents called users which has the properties stream, user and added. I do this to get all documents with a certain user's _id property in there users.user field.
Content.find( { 'users.user': user._id } ).sort( { 'users.added': -1 } )
This seems to work (although I'm unsure if .sort is really working here. However, I want to match two fields, like this:
Content.find( { 'users.user': user._id, 'users.stream': stream } } ).sort( { 'users.added': -1 } )
That does not seem to work. What is the right way to do this?
Here is a sample document

Use $elemMatch operator to specify multiple criteria on an array of embedded documents:
Content.find({"users": {$elemMatch: {"user": user.id, "stream": stream}}});
