• If you are trying to use Boolean operators, they must be ALL CAPS: dong hua wang chua wang yang sun ((((wong sau) OR (wong shiu))) OR (song shin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dong hua wang chua wang yang sun ((((wong sau) OR (wong shiu))) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: dong hua wang chua wang yang sun ((((wong sau) OR (wong shiu))) or (song shin)) ;*.
