title: jquery ui autocomplete: how to match "whitespace" separated query with accurate "comma" separated record
body: <p>I have <b> preloaded</b> xml records on the client side, on which <b>jquery ui autocomplete</b> is applied.<br>
  Say there is a record like this one: <b>"car,bike,plane"</b>. <br></p>
  
  <p>Currently (while using <b>jquery ui autocomplete</b>) if a user types : <b>"car,bike"</b> --> it will find the record mentioned above.
  <br>
  However if the user types: <b>"car bike"</b> (which means instead of <b>comma, a whitespace</b> ) --> no results will be displayed.<br></p>
  
  <p>How to match "car bike" with the given "comma" separated record?</p>
