• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (hoc thieu)) xanh - hinh trinh van phong huong van ((toan cau) OR (toan cao))~.
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (hoc thieu)) xanh - hinh trinh van phong huong van ((toan cau) or (toan cao))*.
