• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach han me giai con thong tin ) or ( bui bich ha ((me nguoi) OR (ma nguoi)) do thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach han me giai con thong tin ) OR ( bui bich ha ((me nguoi) OR (ma nguoi)) do thong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach han me giai con thong tin ) or ( bui bich ha ((me nguoi) OR (ma nguoi)) do thong tin ))*".
