• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chua) OR (theo chu)) xang - ((hang hang) OR (nang sang)) cua cong cong ngang toan cau~.
• Adding a wildcard symbol may retrieve word variants: ((theo chua) or (theo chu)) xang - ((hang hang) or (nang sang)) cua cong cong ngang toan cau*.
