title: IntelliJ IDEA global search
body: <p>I would like to search across projects for variable usages, or at least for strings.  I've got <a href="http://www.indexyourfiles.com/" rel="noreferrer">IndexYourFiles</a> which works well for text searches, but I have to re-index every now and then and would like an integrated solution.  </p>
  
  <p>Is there any way that I can search across projects in IntelliJ IDEA? So far I have only been able to search within the currently-open project.  I'm guessing IntelliJ can't do this natively; are there any plug-ins out there to support this?</p>
  
  <p>Thanks.</p>
