title: Removing filtered text programmatically?
body: <p>I am using GXT's filtered grid(<a href="http://www.sencha.com/examples-2/#filtergrid" rel="nofollow noreferrer">http://www.sencha.com/examples-2/#filtergrid</a>). once the filter is applied i need to remove filtered text whatever user has entered. </p>

  <p>is it possible to remove "abc" text programatically without user intervention?</p>
  
  <p>Thanks!</p>
