• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan OR wing) OR lang) fang yuan chang ch'un yong minh ((cong shin) OR (cong shu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan or wing) or lang) fang yuan chang ch'un yong minh ((cong shin) OR (cong shu)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan or wing) or lang) fang yuan chang ch'un yong minh ((cong shin) OR (cong shu)) ;*.
