• If you are trying to use Boolean operators, they must be ALL CAPS: wenn man tuan hua gain ((((yan liang) OR (you liang))) OR (((yang jin) OR (yang di)))) hong hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wenn man tuan hua gain ((((yan liang) OR (you liang))) or (((yang jin) or (yang di)))) hong hai ;*".
