• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (te sach)) ky nang xa hoi. hieu ((ve cai) OR (va cam)) cuc ban hanh di cua tre~.
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (te sach)) ky nang xa hoi. hieu ((ve cai) or (va cam)) cuc ban hanh di cua tre*.
