Perhaps you should try some spelling variations:
theo chieu » theo tieu, ho chieu, theo chu
chieu sach » chinh sach, chiet tach, chieu sang
thanh dung » thanh duong, thanh tung, thanh hung
hanh dung » anh dung, hanh dong, manh dung
cua nhung » va nhung
cong dan » cong san, cong tan, cong dong
toan tap » toan ban

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: theo chieu sach - ((hanh dung) OR (thanh dung)) cua nhung ((cong dan) or (huong dan)) toan tap~.
• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((hanh dung) OR (thanh dung)) cua nhung ((cong dan) OR (huong dan)) toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((hanh dung) OR (thanh dung)) cua nhung ((cong dan) or (huong dan)) toan tap".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((hanh dung) OR (thanh dung)) cua nhung ((cong dan) or (huong dan)) toan tap*.
