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