• If you are trying to use Boolean operators, they must be ALL CAPS: ((thuoc sach) OR (nuoc sach)) ky nang x hoi. hieu ve ((chat cua) OR (cam xuc)) va dinh cuu cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thuoc sach) OR (nuoc sach)) ky nang x hoi. hieu ve ((chat cua) or (cam xuc)) va dinh cuu cua tre".
