title: jQuery UI Autocomplete use startsWith
body: <p>I'm using the jQuery UI Autocomplete with a local datasource (<code>source: myArray</code>). I want the autocomplete to propose only the results that <em>start with</em> the string entered instead of the default <em>case-insensitive contains</em> search. Is there a simple solution for this or do I have to provide my custom search/source callback?</p>
