• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((canh trang) OR (canh tranh)) va nhung cong ((dan phan) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((canh trang) or (canh tranh)) va nhung cong ((dan phan) OR (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((canh trang) or (canh tranh)) va nhung cong ((dan phan) OR (dan chan)) cau*.
