• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chuc danh) OR (chu manh)) - ((hanh tang) OR (hanh trang)) cua thong cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chu manh)) - ((hanh tang) or (hanh trang)) cua thong cong dan toan cau*.
