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