Get specific part of document

Question

I'm trying Mongo db and I wonder if it's possible to only get a specific part of a document?

For example I have:

{   "name" : "MongoDB",   "info" : { x : 203, y : 102 } } 

and I only want the content of info.

The closest I found is db.collection.find({}, { info: 1 }) but this returns me { "info" : { x : 203, y : 102 } } when I only need { x : 203, y : 102 }.

You could do

db.collection.find({},{'info.x':1, 'info.y':1}) 

but that means listing each and every item of the info object in the projection - which may or may not be what you're looking for.
