• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ((o hoi) or (o hai)). hieu ve cam xuc van nhanh thai ((cau tren) OR (ca tren))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((o hoi) OR (o hai)). hieu ve cam xuc van nhanh thai ((cau tren) OR (ca tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((o hoi) or (o hai)). hieu ve cam xuc van nhanh thai ((cau tren) OR (ca tren))*".
