title: backbone.js collection get vars
body: <p>This seems like an obvious one, but I'm somehow missing it...</p>
  
  <p>How do you send options along with a backbone.js collection fetch()? </p>
  
  <p>Or, from a broader point of view: I have a large dataset on the server, messages in this case, that I want to make accessible through a collection. Seeing as there could be thousands of messages I don't want to simply fetch and store all of them at once, so my collection would have to at least understand limits and offsets. Not to mention querying filtered or sorted lists. </p>
  
  <p>Is a backbone collection even the way to handle this?</p>
  
  <p>Cheers</p>
