• Performing a fuzzy search may retrieve terms with similar spellings: ho hieu lang - manh trung cua nhung ((((cong manh) OR (cong danh))) or (cong dan)) toan cao~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho hieu lang - manh trung cua nhung ((((cong manh) OR (cong danh))) OR (cong dan)) toan cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho hieu lang - manh trung cua nhung ((((cong manh) OR (cong danh))) or (cong dan)) toan cao*".
