• Performing a fuzzy search may retrieve terms with similar spellings: doi chieu sach - ((nhanh trinh) OR (nhanh tinh)) cua nhung cong ((tan toan) or (van toan)) cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((nhanh trinh) OR (nhanh tinh)) cua nhung cong ((tan toan) OR (van toan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((nhanh trinh) OR (nhanh tinh)) cua nhung cong ((tan toan) or (van toan)) cau*".
