• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((((yang jui) OR (yang xi))) OR (yang judy)) hua chen wong john wong shiu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yang jui) OR (yang xi))) or (yang judy)) hua chen wong john wong shiu ;*".
