Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chiet tach » chieu sach
ung trong » dung trong, cung trong, vung trong
tung cao » truong cao, trung cap, quang cao
nung cao » nang cao, nhung cau, quang cao
cac than » cac thanh, cac nhan, cac phan
than cau » toan cau, phan cau, than cap

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 (chiet tach)) - thanh ((tung cao) OR (nung cao)) ung trong cac than cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chiet tach)) - thanh ((tung cao) OR (nung cao)) ung trong cac than cau~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chiet tach)) - thanh ((tung cao) OR (nung cao)) ung trong cac than cau*.
