• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang xa hoi. hieu viec ((cac le) OR (cach le)) van danh vai ((cau treo) or (cau theo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang xa hoi. hieu viec ((cac le) OR (cach le)) van danh vai ((cau treo) OR (cau theo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang xa hoi. hieu viec ((cac le) OR (cach le)) van danh vai ((cau treo) or (cau theo))*".
