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, thuc dan
hanh tang » hanh trang, anh tang, hanh mang
cong tinh » cong trinh, cong vinh, long tinh
toan tap » toan ban
tang va » trang va, tang van, thang va

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