• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang OR wing) OR lang) fang ((yuan kang) OR (yuan chang)) chen yong jie song shin ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or lang) fang ((yuan kang) OR (yuan chang)) chen yong jie song shin ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or lang) fang ((yuan kang) OR (yuan chang)) chen yong jie song shin ;*.
