• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((thieu danh) OR (chieu xanh)) - anh bang ((cua truong) OR (cac truong)) cong van toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((thieu danh) or (chieu xanh)) - anh bang ((cua truong) OR (cac truong)) cong van toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((thieu danh) or (chieu xanh)) - anh bang ((cua truong) OR (cac truong)) cong van toan cau*.
