Perhaps you should try some spelling variations:
doanh xuat » doanh luan, doanh bat
lieu tinh » trieu tinh, diep tinh, bien tinh
doanh cua » doanh luan
tong cong » trong cong, cong cong, dung cong
van thanh » ban thanh, van tuan
van toan » van tuan, van tan, manh toan
ho lieu » so lieu, co lieu, ho kieu

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 lieu tinh - hang ((doanh xuat) OR (doanh cua)) tong cong ((van toan) OR (van thanh)) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho lieu tinh - hang ((doanh xuat) OR (doanh cua)) tong cong ((van toan) or (van thanh)) cao~".
• Adding a wildcard symbol may retrieve word variants: ho lieu tinh - hang ((doanh xuat) OR (doanh cua)) tong cong ((van toan) or (van thanh)) cao*.
