Perhaps you should try some spelling variations:
phuong dinh » phuong binh, phuong linh, phuong trinh
hanh doanh » hang doanh, chinh doanh, doanh doanh
chiet tach » chieu sach
hieu lang » chieu sang, hieu quang, nhieu tang
dinh toan » tinh toan, hinh toan, minh toan
cua theo » cua thep, cua thuoc, chan theo
toan tap » toan ban
cua tho » cua thoi, cua kho, cua tao

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 ((chiet tach) OR (hieu lang)) - hanh doanh ((cua theo) OR (cua tho)) phuong dinh toan tap~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chiet tach) or (hieu lang)) - hanh doanh ((cua theo) OR (cua tho)) phuong dinh toan tap~".
• Adding a wildcard symbol may retrieve word variants: ho ((chiet tach) or (hieu lang)) - hanh doanh ((cua theo) OR (cua tho)) phuong dinh toan tap*.
