Perhaps you should try some spelling variations:
hanh doanh » hang doanh, chinh doanh, doanh doanh
tieu sach » chieu sach, dien sach, te sach
cua trong » cua truong, cua trung, ca trong
qua trong » quan trong, qua trinh, qua song
cong van » cong vang, cong san, song van
van toan » van tuan, van tan, van thanh
toan tap » toan ban

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: theo tieu sach - hanh doanh ((cua trong) OR (qua trong)) cong van toan tap~.
• Adding a wildcard symbol may retrieve word variants: theo tieu sach - hanh doanh ((cua trong) or (qua trong)) cong van toan tap*.
