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