• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu thang ((ma hoa) OR (xa hoi)). hieu vu cham duc ((va hanh) OR (va danh)) lam cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu thang ((ma hoa) or (xa hoi)). hieu vu cham duc ((va hanh) OR (va danh)) lam cua triet".
