Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
thanh tran » thanh trang, thanh tra, thanh tuan
thanh toan » thanh hoa, thanh san, tinh toan
ho chieu » theo chieu, hoc thieu, doi chieu
dan phan » doan phan, dan chan, van phan
phan cau » phan dau, phan cac, phan tu

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 tran) OR (thanh toan)) tuan ((dung cong) OR (dung trong)) dan phan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - ((thanh tran) OR (thanh toan)) tuan ((dung cong) or (dung trong)) dan phan cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - ((thanh tran) OR (thanh toan)) tuan ((dung cong) or (dung trong)) dan phan cau*.
