• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (dong sin)) ya hua ren yang minh ((cong yu) OR (chong yun)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (dong sin)) ya hua ren yang minh ((cong yu) OR (chong yun)) ;".
