• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((ly nang) OR (ky nang)) ((ma hoi) OR (ma hoa)). hieu ve cam duc van hanh thai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((ly nang) OR (ky nang)) ((ma hoi) or (ma hoa)). hieu ve cam duc van hanh thai cua triet*".
