Perhaps you should try some spelling variations:
chieu sang » chieu sach, chieu xanh, hieu lang
doi chieu » doc hieu, doi chi, ho chieu
dung cong » dung trong
ban than » ban thanh, van thanh, ban hang
vat dung » van dung, va dung, viet dung
cong tan » cong tac, cong san, cong thanh
tan toan » tap toan, van toan, dan toan
toan cao » toan ban, toan tap

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sang - ((tan tran) OR (ban than)) vat dung cong tan toan cao~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sang - ((tan tran) OR (ban than)) vat dung cong tan toan cao*.
