• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (lieu tinh)) - hanh trung va phuong cong tan ((can cau) OR (chinh phu))~.
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (lieu tinh)) - hanh trung va phuong cong tan ((can cau) or (chinh phu))*.
