Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
nhung cong » dung cong, thong cong, hang cong
trang cua » tranh cua, trung cua, thang cua
tang cua » mang cua, hang cua, tang luan
cong tac » cong ty
phat lap » phan lap, phat lam, thuat lap
phap lap » phan lap, phap lam, phap luat

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 chieu sach - hanh ((trang cua) OR (tang cua)) nhung cong tac ((phat lap) OR (phap lap))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh ((trang cua) or (tang cua)) nhung cong tac ((phat lap) OR (phap lap))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh ((trang cua) or (tang cua)) nhung cong tac ((phat lap) OR (phap lap))*.
