• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ((ky sang) OR (ky tang)) ma hoa. hieu ve cam duc va dinh vi ((cua te) OR (cua tuc))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ((ky sang) OR (ky tang)) ma hoa. hieu ve cam duc va dinh vi ((cua te) or (cua tuc))*".
