title: Where does brew search search for local taps?
body: <p>I did a <code>brew search ocaml</code> which results in <code>==&gt; Searching local taps...
  ocaml  ocamlbuild  ocamlsdl</code>.  I had removed ocaml from my system, yet it's showing up in the search for local taps. I've tried <code>brew cleanup -s</code> and <code>brew doctor</code> but it didn't fix it.  Thoughts?</p>
