• If you are trying to use Boolean operators, they must be ALL CAPS: wang wing tan ((hua chen) OR (yu chen)) yang dr ((wong siu) OR (kong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wing tan ((hua chen) or (yu chen)) yang dr ((wong siu) OR (kong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wing tan ((hua chen) or (yu chen)) yang dr ((wong siu) OR (kong siu)) ;*.
