• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ty ((nang xa) OR (lang xa)) hoi. hieu ve cam xuc va thanh tai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ty ((nang xa) or (lang xa)) hoi. hieu ve cam xuc va thanh tai cua tre".
