• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((yan yuan) OR (nan yan)) ((lin chen) OR (yi chen)) cheng ming jeong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan yuan) OR (nan yan)) ((lin chen) or (yi chen)) cheng ming jeong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan yuan) OR (nan yan)) ((lin chen) or (yi chen)) cheng ming jeong shu ;*.
