zhong shu » zhang shuo, cong shu, zhong zhi
wang yao » wang yan, gang yao, wang tao
yang yao » yang yang, wang yan, yang fan
chang su » chang hsun, chang fwu, chang gui
su zhong » wu zhong, yu zhong, hua zhong
yang yi » yang di, yang xi, yang jui
yi han » ti han, yi chang

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yao) OR (yang yao)) yang yi han chang su zhong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yao) or (yang yao)) yang yi han chang su zhong shu ;*.
