• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ky nang cao hoa. hieu va cao xuc ca dao vi ((cua su) or (((cua duc) OR (cua tuc))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky nang cao hoa. hieu va cao xuc ca dao vi ((cua su) OR (((cua duc) OR (cua tuc))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ky nang cao hoa. hieu va cao xuc ca dao vi ((cua su) or (((cua duc) OR (cua tuc))))*".
