• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((dong cho) OR (dung cho)) hoc. hieu ve ((cac xuc) OR (cam xuc)) van anh vi cua cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((dong cho) OR (dung cho)) hoc. hieu ve ((cac xuc) or (cam xuc)) van anh vi cua cau*".
