Perhaps you should try some spelling variations:
chieu bang » chu bang, khien bang, chieu xanh
chieu sang » chieu sach, chieu xanh, hieu lang
phuong van » phong van, phuong lan, phuong va
hanh dang » hanh dong, anh dang, hanh dung
dang xay » dang van, van xay
than cau » toan cau, phan cau, than cap

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

• Performing a fuzzy search may retrieve terms with similar spellings: theo ((chieu bang) or (chieu sang)) - hanh dang xay dung ((phuong van) OR (phung van)) than cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo ((chieu bang) OR (chieu sang)) - hanh dang xay dung ((phuong van) OR (phung van)) than cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu bang) or (chieu sang)) - hanh dang xay dung ((phuong van) OR (phung van)) than cau".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu bang) or (chieu sang)) - hanh dang xay dung ((phuong van) OR (phung van)) than cau*.
