Perhaps you should try some spelling variations:
thanh chau » thanh cha, thanh cham, thanh chu
chieu xanh » chieu sach, chieu sang, chieu tinh
ho chieu » theo chieu, hoc thieu, doi chieu
anh bang » anh hoang, anh quang, tinh bang
van dung » van dong, xay dung, tin dung
cong san » cong tac
phan cau » phan dau, phan cac, phan tu
va dung » va duong, vat dung, va ung

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: ho chieu xanh - anh bang ((va dung) OR (van dung)) cong san ((thanh chau) OR (phan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu xanh - anh bang ((va dung) OR (van dung)) cong san ((thanh chau) or (phan cau))~".
• Adding a wildcard symbol may retrieve word variants: ho chieu xanh - anh bang ((va dung) OR (van dung)) cong san ((thanh chau) or (phan cau))*.
