  <p>I have a category indexed for "Mexican Grocery Store" and when I search for that string I am getting zero hits and only a suggest result:</p>

  <p>Not only am I getting zero hits for an exact match but when I type in the string "Mexican" a bunch of categories with the word "Medical" in it are listed before the "Mexican" categories which doesn't make any sense to me either.</p>
