• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach duy sang tao hoi. hieu vu cham duc ((va hanh) OR (((va dinh) OR (van dinh)))) lai chau tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach duy sang tao hoi. hieu vu cham duc ((va hanh) or (((va dinh) OR (van dinh)))) lai chau tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach duy sang tao hoi. hieu vu cham duc ((va hanh) or (((va dinh) OR (van dinh)))) lai chau tre*.
