• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yan) OR (yan yuan)) muxi li sang minh ((cong shu) OR (zhong zhi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yan) OR (yan yuan)) muxi li sang minh ((cong shu) or (zhong zhi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yan) OR (yan yuan)) muxi li sang minh ((cong shu) or (zhong zhi)) ;*.
