Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
cap tong » cap nong, cap hoang, gap trong
cua tong » cua cong, cua dong, cua nong
cong tan » cong tac, cong san, cong thanh
tran ban » tranh ban, toan ban, tran bai
tran van » luan van

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 chinh ((cap tong) OR (cua tong)) cong tan ((tran ban) OR (tran van))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - hanh chinh ((cap tong) or (cua tong)) cong tan ((tran ban) OR (tran van))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - hanh chinh ((cap tong) or (cua tong)) cong tan ((tran ban) OR (tran van))*.
