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