• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky lang ((((ha hoi) OR (hoa hoi))) OR (ha noi)). hieu va cao hoc va thanh tai cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky lang ((((ha hoi) OR (hoa hoi))) or (ha noi)). hieu va cao hoc va thanh tai cua triet*".
