Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhanh long » nhanh dong, thanh long, nhanh song
nhanh lang » nhanh quang, nhanh thang, nhan dang
doi chieu » doc hieu, doi chi, ho chieu
trong tac » trong cac, tuong tac, trong tan
toan cau » toan cao, toan tap, toan tai
toan ban » van ban
va dung » van dung, va duong, vat dung

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 xanh - ((nhanh long) OR (nhanh lang)) va dung trong tac ((toan cau) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: doi chieu xanh - ((nhanh long) or (nhanh lang)) va dung trong tac ((toan cau) or (toan ban))*.
