• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - tranh hang ca dung ((cong manh) OR (duong manh)) toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - tranh hang ca dung ((cong manh) or (duong manh)) toan cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - tranh hang ca dung ((cong manh) or (duong manh)) toan cau*.
