Perhaps you should try some spelling variations:
chieu xanh » chieu sach, chieu sang, chieu tinh
nhung cong » dung cong, thong cong, hang cong
chuc danh » chuc nganh, thuc hanh, chuc nang
thang va » hang va, trang va, thong va
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap
tang va » trang va, tang van, tang vat

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 va) OR (thang va)) nhung cong dan toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chuc danh) or (chieu xanh)) - hanh ((tang va) OR (thang va)) nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: theo ((chuc danh) or (chieu xanh)) - hanh ((tang va) OR (thang va)) nhung cong dan toan cau*.
