Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, hieu manh
chieu tinh » trieu tinh, lieu tinh, chau tinh
canh trang » canh tranh, hanh trang, banh trang
cong dung » cuong dung, cong dong, cong luong
dung toan » dung doanh, dung thang, dung thanh
va duong » van duong, va tuong, va huong
toan cau » toan cao, toan ban, toan tap
va dung » van dung, vat dung, va ung

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((chieu xanh) or (chieu tinh)) - canh trang ((va dung) OR (va duong)) cong dung toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu xanh) OR (chieu tinh)) - canh trang ((va dung) OR (va duong)) cong dung toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu xanh) or (chieu tinh)) - canh trang ((va dung) OR (va duong)) cong dung toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu xanh) or (chieu tinh)) - canh trang ((va dung) OR (va duong)) cong dung toan cau*.
