title: Can I filter find/replace to only search header files in Visual Studio?
body: <p>I am using Find and Replace in Visual Studio 2010.  Currently, I can filter the search to only look in:</p>
  
  <ul>
  <li>the current document</li>
  <li>the selection</li>
  <li>all open documents</li>
  <li>the current project</li>
  <li>the entire solution</li>
  <li>the current block</li>
  </ul>
  
  <p>These are some great filters, but I would like to search only in header files.  Is there a way to search only in header files?</p>
  
  <p>I am currently using <a href="http://tools.tortoisesvn.net/grepWin.html" rel="nofollow">grepWin</a> to search and accomplish this externally to Visual Studio.  Is there a way to search in Visual Studio.  Plugins are acceptable answers.</p>
