Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
trinh luan » trinh quan, trinh han, trinh toan
nhung cong » dung cong, thong cong, hang cong
trinh cua » tinh cua, trinh quan, trinh chat
ho chieu » theo chieu, hoc thieu, doi chieu
cong anh » cong danh, dong anh, hong anh
tuan cao » toan cao, juan cao, quang cao

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 ((((trinh cua) OR (trinh luan))) OR (trinh luat)) nhung cong anh tuan cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh ((((trinh cua) OR (trinh luan))) or (trinh luat)) nhung cong anh tuan cao~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - hanh ((((trinh cua) OR (trinh luan))) or (trinh luat)) nhung cong anh tuan cao*.
