• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((ma hoi) OR (xa hoi)). hieu ve cam duc ban ((thanh lai) OR (phan lap)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((ma hoi) OR (xa hoi)). hieu ve cam duc ban ((thanh lai) or (phan lap)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((ma hoi) OR (xa hoi)). hieu ve cam duc ban ((thanh lai) or (phan lap)) cua tre*.
