• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((tieu xanh) OR (tieu danh)) - canh ((tranh luat) OR (trinh luan)) anh duong van toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((tieu xanh) OR (tieu danh)) - canh ((tranh luat) or (trinh luan)) anh duong van toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((tieu xanh) OR (tieu danh)) - canh ((tranh luat) or (trinh luan)) anh duong van toan cau*.
