• If you are trying to use Boolean operators, they must be ALL CAPS: hoc thieu xanh - ((canh manh) OR (((lanh manh) OR (tuan anh)))) cua bang cong nganh toan cau~.
• Adding a wildcard symbol may retrieve word variants: hoc thieu xanh - ((canh manh) or (((lanh manh) or (tuan anh)))) cua bang cong nganh toan cau*.
