• If you are trying to use Boolean operators, they must be ALL CAPS: (wang OR wing) ((yan yuan) OR (nan yan)) jui chen zhang ming ((wong shiu) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wing) ((yan yuan) OR (nan yan)) jui chen zhang ming ((wong shiu) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wing) ((yan yuan) OR (nan yan)) jui chen zhang ming ((wong shiu) or (wong siu)) ;*.
