• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky nang ((cao hoi) OR (co hoi)). hieu vu cham xuc ((va hanh) or (va dan)) dau cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky nang ((cao hoi) OR (co hoi)). hieu vu cham xuc ((va hanh) OR (va dan)) dau cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky nang ((cao hoi) OR (co hoi)). hieu vu cham xuc ((va hanh) or (va dan)) dau cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky nang ((cao hoi) OR (co hoi)). hieu vu cham xuc ((va hanh) or (va dan)) dau cua tre*.
