• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo tieu)) xanh - thanh trung cua dang ((dung dan) OR (tung dan)) toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo tieu)) xanh - thanh trung cua dang ((dung dan) OR (tung dan)) toan cau*".
