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