• If you are trying to use Boolean operators, they must be ALL CAPS: ((hoc chieu) OR (ho chieu)) sach - manh trung qua dung cong van ((than cap) OR (thanh cac))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc chieu) OR (ho chieu)) sach - manh trung qua dung cong van ((than cap) or (thanh cac))*".
