• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tu sach) OR (thu sach))) OR (su sach)) ty hang va hoi. hieu ve tam thuc day danh vu cua te~.
• Adding a wildcard symbol may retrieve word variants: ((((tu sach) or (thu sach))) or (su sach)) ty hang va hoi. hieu ve tam thuc day danh vu cua te*.
