• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((chang ch'un) OR (yi chen)) yan wang ((yang jie) OR (yang jin)) ((hong ng) OR (chang ha)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((chang ch'un) or (yi chen)) yan wang ((yang jie) OR (yang jin)) ((hong ng) or (chang ha)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((chang ch'un) or (yi chen)) yan wang ((yang jie) OR (yang jin)) ((hong ng) or (chang ha)) ;*.
