Don -- I think if you went to that "sun visor" listing you will see any one of the three words: casino, poker or chip(s) in the description, as you selected "Title and Description" in your search. Keep in mind that the word "chip" has a few other definitions when used by itself.

To answer your second question: Try both ways to see which you like best...and, of course, keep your search narrow at first and progress a little at a time -- with trying to understand that all of eBay Auctions is nothing more than "one big room" with nothing being hidden. It's just knowing where to look to see what's listed, and they give you every possible option to find what you're looking for.
