• Performing a fuzzy search may retrieve terms with similar spellings: ((te sach) OR (toc sach)) ky nang ((x hoi) or (x ho)). hieu van cam xuc va dinh dinh cau theo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sach) OR (toc sach)) ky nang ((x hoi) OR (x ho)). hieu van cam xuc va dinh dinh cau theo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sach) OR (toc sach)) ky nang ((x hoi) or (x ho)). hieu van cam xuc va dinh dinh cau theo".
• Adding a wildcard symbol may retrieve word variants: ((te sach) OR (toc sach)) ky nang ((x hoi) or (x ho)). hieu van cam xuc va dinh dinh cau theo*.
