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