• Performing a fuzzy search may retrieve terms with similar spellings: (( thu sach ca ((me gioi) OR (me nguoi)) con hong tin ) or ( tu sach cha ve gioi con tdong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thu sach ca ((me gioi) OR (me nguoi)) con hong tin ) OR ( tu sach cha ve gioi con tdong tinh ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu sach ca ((me gioi) OR (me nguoi)) con hong tin ) or ( tu sach cha ve gioi con tdong tinh ))*".
