• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu xanh - nhanh mang va nhung cong danh ((((toan cau) OR (toan tai))) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - nhanh mang va nhung cong danh ((((toan cau) or (toan tai))) or (toan cao))*.
