• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (hoc thieu)) xanh - manh ban thanh hang cong ((dan toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (hoc thieu)) xanh - manh ban thanh hang cong ((dan toan) OR (van toan)) cau".
