• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sach)) - thanh thanh va dung trong ((van tan) OR (van tuan)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sach)) - thanh thanh va dung trong ((van tan) or (van tuan)) cao*".
