• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu sang)) - hanh trang cua cong song van ((thanh cau) OR (thanh chau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu sang)) - hanh trang cua cong song van ((thanh cau) OR (thanh chau))*".
