title: Search all Git branches for a keyword
body: <p>I swear I wrote a test called "heartbeatTest" or "heartbeatRouteTest" in one of the branches of a Git repository.</p>
  
  <p>But I can't find it in any of the branches. Is there a way to do a global search with Git to find a matching phrase in any branch for a particular local/remote repository?</p>
