• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach ky dang ((me hoi) OR (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) van hang va cuc tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach ky dang ((me hoi) or (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) van hang va cuc tre".
• Adding a wildcard symbol may retrieve word variants: nuoc sach ky dang ((me hoi) or (xa hoi)). hieu ve ((cac xuc) OR (cam xuc)) van hang va cuc tre*.
