• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi chieu) OR (ho chieu)) sach - hanh trung ((cua bang) OR (cua dang)) phuong danh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi chieu) or (ho chieu)) sach - hanh trung ((cua bang) OR (cua dang)) phuong danh toan cau".
• Adding a wildcard symbol may retrieve word variants: ((thi chieu) or (ho chieu)) sach - hanh trung ((cua bang) OR (cua dang)) phuong danh toan cau*.
