• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - ((((dang trung) OR (dinh trung))) OR (manh hung)) hua khong quang manh toan cau~.
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - ((((dang trung) or (dinh trung))) or (manh hung)) hua khong quang manh toan cau*.
