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