• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) dang xa hoi. thien ((van cam) OR (van nam)) duc va danh va cau triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) dang xa hoi. thien ((van cam) OR (van nam)) duc va danh va cau triet*.
