• If you are trying to use Boolean operators, they must be ALL CAPS: chao ((chu xanh) OR (chieu xanh)) - ((anh mang) OR (anh dong)) va thong cong dan toan cau~.
• Adding a wildcard symbol may retrieve word variants: chao ((chu xanh) or (chieu xanh)) - ((anh mang) or (anh dong)) va thong cong dan toan cau*.
