• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chiet) OR (thep thiet)) tach - thanh ((tuong so) OR (thuong su)) dung trong ban hang cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chiet) OR (thep thiet)) tach - thanh ((tuong so) or (thuong su)) dung trong ban hang cau*".
