• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu hang tao hoi. hieu vu cham duc ((((va hanh) OR (ban hanh))) OR (va dan)) lai cho tre~.
• Adding a wildcard symbol may retrieve word variants: su sach tu hang tao hoi. hieu vu cham duc ((((va hanh) or (ban hanh))) or (va dan)) lai cho tre*.
