• If you are trying to use Boolean operators, they must be ALL CAPS: hoc hieu manh - hanh trang cua tong cong ((xuan toan) OR (((manh toan) OR (anh tuan)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc hieu manh - hanh trang cua tong cong ((xuan toan) or (((manh toan) OR (anh tuan)))) cau~".
• Adding a wildcard symbol may retrieve word variants: hoc hieu manh - hanh trang cua tong cong ((xuan toan) or (((manh toan) OR (anh tuan)))) cau*.
