Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh toan » thanh hoa, thanh san, tinh toan
tuan duong » tuyen duong, tuong duong, van duong
thanh tra » thanh hoa
ho chieu » theo chieu, hoc thieu, doi chieu
cong nam » dong nam, thong nam, trong nam
uong nam » dong nam, quang nam, thong nam
toan tap » toan 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: ho chieu sach - ((thanh tra) OR (thanh toan)) tuan duong ((cong nam) OR (uong nam)) toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh tra) or (thanh toan)) tuan duong ((cong nam) OR (uong nam)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh tra) or (thanh toan)) tuan duong ((cong nam) OR (uong nam)) toan tap*.
