• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang ((x hoi) OR (xa hoi)). hieu ve ((cau luc) OR (cam xuc)) tuan anh vi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang ((x hoi) OR (xa hoi)). hieu ve ((cau luc) or (cam xuc)) tuan anh vi cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ly nang ((x hoi) OR (xa hoi)). hieu ve ((cau luc) or (cam xuc)) tuan anh vi cua tre*.
