title: Can I do a wildcard (*) search on github.com?
body: <p>I want to search a repository for any files that end in <code>*Test.java*</code> but if I search for <code>*Test.java*</code> I just get files that contain that exact string.</p>
  
  <p>I can't find any information anywhere that suggests this is possible. Is this just due to limitations of indexing such an enormous amount of data?</p>
  
  <p>I'd like to find a way to search a repo for all classes ending in <code>Test</code>.</p>
