• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky lang ((van hoi) OR (van hoa)). hieu va cham ((loc gia) OR (toc gia)) thanh tri cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky lang ((van hoi) or (van hoa)). hieu va cham ((loc gia) OR (toc gia)) thanh tri cua triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky lang ((van hoi) or (van hoa)). hieu va cham ((loc gia) OR (toc gia)) thanh tri cua triet*.
