Of course! It just depends on where you write your subscriptions. In a lot of cases you might be using Iron Router, in which case you would have a given route subscribe to just the data that you need. Then from within that route template's helper you can only query documents within that subscription.

But the general idea is that you hook up a particular subscription to a particular template.

Template.onePost.helpers({
  post: function() {
    Meteor.subscribe('just-one-post', );
    return Posts.findOne();
  }
});

Template.allPosts.helpers({
  posts: function() {
    Meteor.subscribe('all-posts');
    return Posts.find();
  }
));
