wing tan » wing ian, liang tan, hong tan
tan kai » tan kah, yuan kai
hong g » hong ng, hong 7, hong ghi
hong a » hong ma, kong a, hong 7

• If you are trying to use Boolean operators, they must be ALL CAPS: wing tan kai a test ((yang judy) OR (than change)) ((((hong g) OR (hong a))) OR (hong w)) ;~.
• Adding a wildcard symbol may retrieve word variants: wing tan kai a test ((yang judy) or (than change)) ((((hong g) or (hong a))) or (hong w)) ;*.
