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