Perhaps you should try some spelling variations:
nhung phuong » dung phuong, nhu phuong, truong phuong
chieu sach » chinh sach, chiet tach, chieu sang
trinh toan » thanh toan, trinh han, trinh quan
doi chieu » doc hieu, doi chi, ho chieu
dan toan » van toan, dan than, manh toan
ban than » ban thanh, van thanh, ban hang

You may be able to get more results by adjusting your search query.

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