• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang wang) OR (wang yan)) liang 2 best book chang ((chong suk) OR (shen zuo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yan)) liang 2 best book chang ((chong suk) or (shen zuo)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yan)) liang 2 best book chang ((chong suk) or (shen zuo)) ;*.
