title: How to not get NSSearchField freezing?
body: <p>I've got a NSSearchField, whose action method does all the searching stuff, by analyzing the sender argument (string).</p>
  
  <p>Now the searching stuff (feeding a large array) is kind of CPU intensive, which lets my search field freeze for some seconds.<br>
  In other cases i'd detach another NSThread to prevent my GUI from freezing. But in this case that is not possible, because I would detach another ("search") thread everytime the user enters another letter in the search field.</p>
  
  <p>Is there another way of keeping my NSSearchField from freezing?</p>
  
  <p>BTW: My guess is NO, because even the Developoer Documentation's seach field freezes all the time :)</p>
