• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien hanh)) - hanh trung ((phan chung) OR (phan cung)) cong sang than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien hanh)) - hanh trung ((phan chung) OR (phan cung)) cong sang than cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((hien xanh) or (hien hanh)) - hanh trung ((phan chung) OR (phan cung)) cong sang than cau*.
