• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu manh) OR (tien manh)) - hanh trung ((cua dung) OR (qua dung)) cong danh toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu manh) OR (tien manh)) - hanh trung ((cua dung) or (qua dung)) cong danh toan cao".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu manh) OR (tien manh)) - hanh trung ((cua dung) or (qua dung)) cong danh toan cao*.
