Perhaps you should try some spelling variations:
chieu sach » chinh sach, chiet tach, chieu sang
hanh doanh » hang doanh, chinh doanh, doanh doanh
doanh luan » doanh nhan
thong cong » trong cong, thong thong, phong chong
doi chieu » doc hieu, doi chi, mot chieu
tong cong » trong cong, cong cong, dung cong
tran tap » toan tap, tran tan, tran tuan

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "doi chieu sach - hanh doanh luan ((thong cong) OR (tong cong)) tan tran tap~".
• Adding a wildcard symbol may retrieve word variants: doi chieu sach - hanh doanh luan ((thong cong) OR (tong cong)) tan tran tap*.
