• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang ka ((hua ren) OR (yu cheng)) chan fong ((hong shu) OR (wong shiu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ka ((hua ren) or (yu cheng)) chan fong ((hong shu) OR (wong shiu)) ;".
