Perhaps you should try some spelling variations:
chieu xanh » chieu sang, hieu manh
chieu sach » chinh sach, chiet tach, chieu sang
chieu tinh » trieu tinh, lieu tinh, chau tinh
thanh tung » thanh cong
dung cong » dung trong
cong dan » cong san, cong tan, huong dan
dan than » dan chan, ban than, van than
than cau » toan cau, phan cau, than cap
tung ap » tang ap, tung dan, tung bay
ap dung » xay dung, van dung

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: doi ((((chieu xanh) OR (chieu sach))) OR (chieu tinh)) - thanh tung ap dung cong dan than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doi ((((chieu xanh) OR (chieu sach))) or (chieu tinh)) - thanh tung ap dung cong dan than cau~".
• Adding a wildcard symbol may retrieve word variants: doi ((((chieu xanh) OR (chieu sach))) or (chieu tinh)) - thanh tung ap dung cong dan than cau*.
