• If you are trying to use Boolean operators, they must be ALL CAPS: co sach tao nano xa hoi. hieu ve cam xuc van hanh va ((cua tre) OR (((cau treo) OR (cau triet)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "co sach tao nano xa hoi. hieu ve cam xuc van hanh va ((cua tre) or (((cau treo) OR (cau triet))))".
