Get the identifier of the affected document using update ()

Question

I use this to do upsert:

Articles.update(
    { title: title },
    { 
        title: title,
        parent: type
    },
    { upsert: true }, 
    function(res) {
        return console.log(res);
    }
);

console.log(needToGetID);

Now I need to get the _id of the document that has been updated or inserted. I thought I could get this through a callback, but res- undefined. I assume that there is only one unique document that is defined by the request.

Update

Forgot to mention that I use a meteorite ...
