Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
chuc danh » chuc nganh, thuc hanh, chuc nang
hanh tang » hanh trang, anh tang, hanh mang
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
tang su » tang suc, trang su, dang su

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: theo ((chuc danh) OR (chieu xanh)) - hanh tang su dung cong dan than cau~.
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu xanh)) - hanh tang su dung cong dan than cau*.
