It seems to me that you consider "fast searchers" not knowledge based (please correct me if I am misunderstanding your statements, I do not want to put words in your mouth). I think a fast searcher can have lots of knowledge (not in the evaluation function, of course). Still I do not know if they qualify as "knowledge based". José.
