How to add search filters like those in Finder?

• Maya Trifonova How to add search filters like those in Finder? Apr 26 2010, 13:25
  Hi all,
  
  I need to implement add/remove filters for search results like those
  in Finder with the "+" and "-" and "save search" buttons (Those that
  appear under the spotlite search field when something is typed in it).
  When the "+" button is pushed another filter appears with popup
  buttons like "Kind", "Last open date", "Last modified date". When the
  "-" is pushed the filter disappears.
  
  My question is.. what kind of cocoa UI element is the whole line (with
  the add/remove buttons and popup buttons) and how should I implement
  showing and hiding? I couldn't find sample code with similar UI
  elements.
  
  Regards,
  Maya

  You probably want either NSRuleEditor or NSPredicateEditor.

  You want NSPredicateEditor.
