• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (thi chieu)) xanh - canh manh ((cua dung) OR (qua dung)) cong dan chan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (thi chieu)) xanh - canh manh ((cua dung) OR (qua dung)) cong dan chan cau*".
