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