Perhaps you should try some spelling variations:
nhanh cong » nhanh chong, nhanh dong, hanh cong
nganh cong » nhanh chong
nhung cong » dung cong, thong cong, hang cong
tieu sach » chieu sach, dien sach, te sach
cua nhung » va nhung
cong san » cong tac
san toan » van toan, dan toan, manh toan
toan ban » van ban

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 tieu sach - ((((nhanh cong) OR (nganh cong))) OR (thanh cong)) cua nhung cong san toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo tieu sach - ((((nhanh cong) OR (nganh cong))) or (thanh cong)) cua nhung cong san toan ban~".
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - ((((nhanh cong) OR (nganh cong))) or (thanh cong)) cua nhung cong san toan ban*.
