• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) tu dong xay hoi. hieu ((va cao) OR (va cac)) xuc van dinh lam cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) tu dong xay hoi. hieu ((va cao) or (va cac)) xuc van dinh lam cua triet".
