• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach ((che ve) OR (che vi)) nguoi co thong tin ) or ( te sach ha vien gioi con thong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach ((che ve) OR (che vi)) nguoi co thong tin ) OR ( te sach ha vien gioi con thong tin ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach ((che ve) OR (che vi)) nguoi co thong tin ) or ( te sach ha vien gioi con thong tin ))*".
