• If you are trying to use Boolean operators, they must be ALL CAPS: doi chieu sach - ((canh doanh) OR (hanh doanh)) cua nhung tang ((van toan) OR (van tuan)) ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - ((canh doanh) or (hanh doanh)) cua nhung tang ((van toan) OR (van tuan)) ban~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - ((canh doanh) or (hanh doanh)) cua nhung tang ((van toan) OR (van tuan)) ban*.
