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