• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (trieu tinh)) - hanh trang ((luan dung) OR (luan dong)) cong tap doan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (trieu tinh)) - hanh trang ((luan dung) OR (luan dong)) cong tap doan tap".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) or (trieu tinh)) - hanh trang ((luan dung) OR (luan dong)) cong tap doan tap*.
