Excellent and gracious answer, HotBulge (and thanks for it). May I add that, if you put more than one word in the search tool, it searches for either of those words.
Which means that searching for "John Barrowman" will also reveal search results for John Travolta, Elton John, and all sorts of other people with John in their name. You'll find your results more quickly if you search for just "Barrowman".
