Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trang cua » tang cua, trung cua, thang cua
tranh cua » doanh cua, manh cua
ho chieu » theo chieu, hoc thieu, doi chieu
cong san » cong tac
cong tan » cong tac, cong thanh, cong ty
toan cau » toan cao, toan ban, toan tap

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 - hanh ((trang cua) OR (tranh cua)) nhung ((cong san) OR (cong tan)) toan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((trang cua) OR (tranh cua)) nhung ((cong san) or (cong tan)) toan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((trang cua) OR (tranh cua)) nhung ((cong san) or (cong tan)) toan cau*.
