• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve cam thu day hanh di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (so sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve cam thu day hanh di cua tre".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (so sach)) y ((nang xa) OR (lang xa)) hoi. hieu ve cam thu day hanh di cua tre*.
