• If you are trying to use Boolean operators, they must be ALL CAPS: wing yan phang hua gene zhang jin ((won sau) OR (((wong sau) OR (((wong siu) OR (kong siu)))))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan phang hua gene zhang jin ((won sau) or (((wong sau) or (((wong siu) OR (kong siu)))))) ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan phang hua gene zhang jin ((won sau) or (((wong sau) or (((wong siu) OR (kong siu)))))) ;*.
