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