• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - nhanh lang ((cua trung) OR (xuan trung)) uong dan toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - nhanh lang ((cua trung) or (xuan trung)) uong dan toan tap".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sach)) - nhanh lang ((cua trung) or (xuan trung)) uong dan toan tap*.
