title: Searching for a repo in Github APIv3
body: <p>I know how to search for a repository by providing key words in Github APIv2 .But is this possible in the APIv3? 
  <a href="http://develop.github.com/p/repo.html" rel="nofollow">http://develop.github.com/p/repo.html</a>
  It says 
  "This API is deprecated. Check out API v3 for the latest documentation."
  But I would like to do the same search operation in APIv3. Is this possible?
  Please help.....</p>
