• If you are trying to use Boolean operators, they must be ALL CAPS: thep tieu can - hanh tang cua khong cong ban ((than cau) OR (((toan cau) OR (toan ban))))~.
• Adding a wildcard symbol may retrieve word variants: thep tieu can - hanh tang cua khong cong ban ((than cau) or (((toan cau) or (toan ban))))*.
