• If you are trying to use Boolean operators, they must be ALL CAPS: yuan ((kang tao) OR (huang tao)) ((a chen) OR (z chen)) ((yang jin) OR (chan ming)) wang yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan ((kang tao) OR (huang tao)) ((a chen) or (z chen)) ((yang jin) or (chan ming)) wang yue ;~".
• Adding a wildcard symbol may retrieve word variants: yuan ((kang tao) OR (huang tao)) ((a chen) or (z chen)) ((yang jin) or (chan ming)) wang yue ;*.
