• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sach - manh tuong cua dung trong lang ((((thang cau) OR (hang cau))) or (thanh phan))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - manh tuong cua dung trong lang ((((thang cau) OR (hang cau))) OR (thanh phan))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - manh tuong cua dung trong lang ((((thang cau) OR (hang cau))) or (thanh phan))*".
