• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yan) OR (((wei yang) OR (wei yang's)))) gan yi chen zheng mun leong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (((wei yang) OR (wei yang's)))) gan yi chen zheng mun leong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (((wei yang) OR (wei yang's)))) gan yi chen zheng mun leong shu ;*.
