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