title: What does autocomplete request/server response look like?
body: <p>This seems to be a black hole: After an hour of searching the <a href="http://en.wikipedia.org/wiki/JQuery_UI" rel="noreferrer">jQuery UI</a> website, Stack&nbsp;Overflow, and googling, I've yet to find the most basic information of how to write the <em>server side</em> of the AutoComplete.</p>
  
  <p>What parameter is passed to the server and what should the JSON response look like?</p>
  
  <p>I must be missing something, because how did everyone else learn how to do this? Sites only seem to discuss the client-side JavaScript code and never the protocol or server-side examples.</p>
  
  <p>I need enough to get the simplest remote example working.</p>
