• If you are trying to use Boolean operators, they must be ALL CAPS: hoc chieu xanh - hanh trung ((van dang) OR (van nang)) cong tac ((than cau) OR (phan cau))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - hanh trung ((van dang) OR (van nang)) cong tac ((than cau) or (phan cau))*".
