• If you are trying to use Boolean operators, they must be ALL CAPS: wing ian ((((wang hui) OR (wang hua))) OR (yang jui)) i sang minh ((wong shiu) OR (zhang zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ian ((((wang hui) OR (wang hua))) or (yang jui)) i sang minh ((wong shiu) or (zhang zhi)) ;*".
