• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - thanh truong ca dang ((((cong tan) OR (cong thanh))) or (cong tac)) toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - thanh truong ca dang ((((cong tan) OR (cong thanh))) OR (cong tac)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh truong ca dang ((((cong tan) OR (cong thanh))) or (cong tac)) toan cao*".
