• If you are trying to use Boolean operators, they must be ALL CAPS: ((((thu sach) OR (thuoc sach))) OR (tu sach)) ty hang xa hoi. hieu va cam duc van hanh vi cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((((thu sach) or (thuoc sach))) or (tu sach)) ty hang xa hoi. hieu va cam duc van hanh vi cua tre*.
