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