• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (dong sin)) ((ka a) OR (k a)) west book third ((hong ghi) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dong sin)) ((ka a) or (k a)) west book third ((hong ghi) OR (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dong sin)) ((ka a) or (k a)) west book third ((hong ghi) OR (zhong zhi)) ;*.
