• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thien anh) OR (tien anh)) - ((hanh truong) OR (anh truong)) cua khong thong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc ((thien anh) or (tien anh)) - ((hanh truong) or (anh truong)) cua khong thong dan toan cau*.
