• Performing a fuzzy search may retrieve terms with similar spellings: (("te sach hoc dan nguoi") or ((("tu sach hoa dam nguoi") OR ("tu sach hoi dam nguoi"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("te sach hoc dan nguoi") OR ((("tu sach hoa dam nguoi") OR ("tu sach hoi dam nguoi"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"te sach hoc dan nguoi\") or (((\"tu sach hoa dam nguoi\") OR (\"tu sach hoi dam nguoi\"))))*".
• Removing quotes may allow a broader search: (( te sach hoc dan nguoi ) or ((( tu sach hoa dam nguoi ) OR ( tu sach hoi dam nguoi ))))*.
