• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yan ((yu chen) OR (yu cheng)) ((((chan eng) OR (chan fong))) OR (chan ming)) chun h ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yan ((yu chen) or (yu cheng)) ((((chan eng) OR (chan fong))) or (chan ming)) chun h ;*".
