• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - thanh trung ((thao duong) OR (tac dung)) cong tran thanh cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - thanh trung ((thao duong) or (tac dung)) cong tran thanh cap".
