title: IntelliJ Ultimate 14 find usages not working
body: <p>I am using IntelliJ IDEA 14 Ultimate. When I search find usages, in find view, there is an info like &quot;Searching for usages in project files&quot; and doesn't return any result. Scope is &quot;whole project&quot;.</p>
  <p>I have also IntelliJ 14 Community Edition. When it tries find usages in Community Edition, it works.</p>
  <p>Do you have any idea?</p>
