Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
hanh tran » hanh trang, thanh tran, hanh tram
van dung » van dong, xay dung
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan cau » toan cao, toan ban, toan tap

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

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