• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (te sach)) ky nang co hai. hieu da nang luc ((van anh) OR (van thanh)) vi cua viet~.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (te sach)) ky nang co hai. hieu da nang luc ((van anh) or (van thanh)) vi cua viet*.
