• If you are trying to use Boolean operators, they must be ALL CAPS: ((wan yang) OR (dan yang)) yang hua ((shiyan chang) OR (chin chang)) tin hong yu ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yang) OR (dan yang)) yang hua ((shiyan chang) or (chin chang)) tin hong yu ;*".
