• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sang - ((((anh sang) OR (anh dung))) OR (hanh mang)) cua hang dong san toan cau~.
• Adding a wildcard symbol may retrieve word variants: theo chieu sang - ((((anh sang) or (anh dung))) or (hanh mang)) cua hang dong san toan cau*.
