• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - ((((hanh tung) OR (hanh dung))) OR (nhanh mang)) cua nong cong tap toan ban~.
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - ((((hanh tung) or (hanh dung))) or (nhanh mang)) cua nong cong tap toan ban*.
