• If you are trying to use Boolean operators, they must be ALL CAPS: ((((doc sach) OR (hoc sach))) OR (thuat sach)) ky sang xa hoi. hieu ve cam tu va hanh ca cua tri~.
• Adding a wildcard symbol may retrieve word variants: ((((doc sach) or (hoc sach))) or (thuat sach)) ky sang xa hoi. hieu ve cam tu va hanh ca cua tri*.
