• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach cac moi gioi ((cau tdong) OR (cau trong)) tin ) or ( tu sach xa ke nguoi ho hong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach cac moi gioi ((cau tdong) OR (cau trong)) tin ) OR ( tu sach xa ke nguoi ho hong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach cac moi gioi ((cau tdong) OR (cau trong)) tin ) or ( tu sach xa ke nguoi ho hong tin ))*".
