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