• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien khang) OR (hien khanh)) - hanh trung tuan nhung duong ((manh toan) OR (tinh toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien khang) or (hien khanh)) - hanh trung tuan nhung duong ((manh toan) OR (tinh toan)) cao".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien khang) or (hien khanh)) - hanh trung tuan nhung duong ((manh toan) OR (tinh toan)) cao*.
