• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu xanh) OR (chieu sang)) - anh son luon dang cong ((van tan) OR (van ban)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) or (chieu sang)) - anh son luon dang cong ((van tan) OR (van ban)) cau*".
