title: Custom search for jQuery FancyTree plugin
body: <p>I'm using the FancyTree jQuery plugin in one of my projects: <a href="https://github.com/mar10/fancytree">https://github.com/mar10/fancytree</a></p>
  
  <p>This plugin also has a Filter extension which either dimms or hides the unmatched nodes: <a href="https://github.com/mar10/fancytree/wiki/ExtFilter">https://github.com/mar10/fancytree/wiki/ExtFilter</a></p>
  
  <p>My tree is a two-level tree, it means that there are folders which have children. What I try to do is - search by both Folder name and nodes names. The problem is that when you have something like this:</p>
  
  <p>Node Title
    - Node child
    - Node child 2</p>
  
  <p>Searching by "Title" will leave the folder "Node Title" and hide the children since there's no "Title" in them.</p>
  
  <p>What I want to do is - search by both folder name and children names but don't hide the children - hide the unmatched folders only.</p>
  
  <p>So, when you search by "Title" - it will hide all the folders which do not have "Title" in them but leave the child nodes of "Node Title" folder intact - visible.</p>
  
  <p>Could anybody help me with an advise on how can this be done?</p>
  
  <p>Thanks beforehand!</p>
