• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (dong skin)) ya hua test ((yang mind) OR (yang jin)) ((hong ghi) OR (zhong zhi)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (dong skin)) ya hua test ((yang mind) or (yang jin)) ((hong ghi) OR (zhong zhi)) ;*".
