• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((((chua xang) OR (chieu xanh))) OR (chu han)) - hanh dung luan thong cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((((chua xang) or (chieu xanh))) or (chu han)) - hanh dung luan thong cong dan toan cau*.
