Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
quang tuan » quang thanh, quan luan, quang cua
thanh tan » thanh toan, thanh tuan, thanh san
tran dung » tran dang, tran hung, tran quang
cong tran » cong tan, cong tuan, cong tren
cong toan » cong tan, cong hoan, cong tuan

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: mot chieu sach - thanh tan tran dung ((cong tran) OR (cong toan)) quang tuan~.
• Adding a wildcard symbol may retrieve word variants: mot chieu sach - thanh tan tran dung ((cong tran) or (cong toan)) quang tuan*.
