• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (theo chieu)) xanh - thanh trung cua dang ((dong bang) or (dong thanh)) phan cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (theo chieu)) xanh - thanh trung cua dang ((dong bang) or (dong thanh)) phan cau*.
