Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
cong hoan » cong hoa, cong san, cong ha
thanh lap » thanh san, phan lap, thanh hai
ho chieu » theo chieu, hoc thieu, doi chieu
tung cua » trung cua, tuong cua, tang cua
dung cua » dung luan, dung cho
dong hoa » dong hoc, dong co

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 ((tung cua) OR (dung cua)) nhung ((cong hoan) OR (dong hoa)) thanh lap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh ((tung cua) OR (dung cua)) nhung ((cong hoan) or (dong hoa)) thanh lap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh ((tung cua) OR (dung cua)) nhung ((cong hoan) or (dong hoa)) thanh lap*.
