• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((((sach ky) OR (sach y))) OR (sach thu)) nang xa hoi. hieu van cham loc van hanh di cua triet~.
• Adding a wildcard symbol may retrieve word variants: thu ((((sach ky) or (sach y))) or (sach thu)) nang xa hoi. hieu van cham loc van hanh di cua triet*.
