Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tung » thanh cong
ho chieu » theo chieu, hoc thieu, doi chieu
van dung » van dong, xay dung, tin dung
cong dan » cong san, huong dan, cong dong
cong tan » cong tac, cong san, cong thanh
than cap » khan cap, thanh lap, thanh cac

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: ho chieu sach - ((thanh trung) OR (thanh tung)) van dung ((cong dan) OR (cong tan)) than cap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh trung) OR (thanh tung)) van dung ((cong dan) or (cong tan)) than cap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh trung) OR (thanh tung)) van dung ((cong dan) or (cong tan)) than cap*.
