• If you are trying to use Boolean operators, they must be ALL CAPS: wang yong ((yan juan) OR (yan yuan)) rene ((yang jun) OR (yang xi)) ((wong sam) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yong ((yan juan) OR (yan yuan)) rene ((yang jun) or (yang xi)) ((wong sam) or (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yong ((yan juan) OR (yan yuan)) rene ((yang jun) or (yang xi)) ((wong sam) or (wong shiu)) ;*.
