• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sac) OR (su xac)) ky dang ((ha hoi) OR (hoa hoi)). hieu va chat duc va hanh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sac) or (su xac)) ky dang ((ha hoi) OR (hoa hoi)). hieu va chat duc va hanh vi cua triet*".
