• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien nhanh)) - nhanh quan hanh nhu phuong ((dan toan) OR (van thanh)) cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien nhanh)) - nhanh quan hanh nhu phuong ((dan toan) or (van thanh)) cau*.
