• If you are trying to use Boolean operators, they must be ALL CAPS: wang wang ((yan jui) OR (yang hui)) li rong minh ((cong shu) OR (tong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang wang ((yan jui) OR (yang hui)) li rong minh ((cong shu) or (tong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang ((yan jui) OR (yang hui)) li rong minh ((cong shu) or (tong hui)) ;*.
