It is sometimes difficult to come up with an effective set of keywords to search for items of interest on eBay and other places like SAN. I wonder if anyone is working on or has already developed an AI that can take free form input and turn it into an effective search of auction sites? It would be wonderful to put in something like "Give me all items listed that have something to do with auto racing" and get back relevant results rather than air races, horse races, boat races, race relations, politics, and other stuff that has nothing to do with auto racing. That is just one example; I've had similar results when searching for nearly everything I've ever had an interest in.
