Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh hang » thanh hoang, thanh thang, tranh hang
ho chieu » theo chieu, hoc thieu, doi chieu
cap dung » cao dung, chan dung, cach dung
cong dan » cong san, cong tan, huong dan
than tap » toan tap, phan tap, than cap
ap dung » xay dung, van dung
han tap » han tai, toan tap, nhan tai

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 hang ((cap dung) OR (ap dung)) cong dan ((than tap) OR (han tap))~.
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh hang ((cap dung) or (ap dung)) cong dan ((than tap) or (han tap))*.
