• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang yan)) han china wen gang 3 ((long d) OR (long do)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yan)) han china wen gang 3 ((long d) OR (long do)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yan)) han china wen gang 3 ((long d) OR (long do)) ;*.
