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