Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu tinh, hieu manh
chieu sang » chieu sach, hieu lang, nhieu tang
cong thanh » dong thanh, cong trinh, cong tan
cong manh » cong danh, duong manh, hoang manh
canh anh » anh anh, canh tranh, thanh anh
toan cau » toan cao, toan ban, toan tap
va dang » van dang, va nang, va lang
anh va » hanh va

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) OR (chieu sang)) - canh anh va dang ((cong manh) OR (cong thanh)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sang)) - canh anh va dang ((cong manh) or (cong thanh)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sang)) - canh anh va dang ((cong manh) or (cong thanh)) toan cau*.
