Perhaps you should try some spelling variations:
hanh doanh » chinh doanh, doanh doanh, kinh doanh
hang doanh » nhung doanh, van doanh, dung doanh
luan nang » luan van, van nang, luan san
song danh » song hanh, cong danh, song xanh
danh toan » manh toan, anh toan, dan toan
ho chieu » theo chieu, hoc thieu, doi chieu
toan ban » van 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: ((hoc hien) OR (ho chieu)) xanh - ((hanh doanh) OR (hang doanh)) luan nang song danh toan ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc hien) or (ho chieu)) xanh - ((hanh doanh) OR (hang doanh)) luan nang song danh toan ban~".
• Adding a wildcard symbol may retrieve word variants: ((hoc hien) or (ho chieu)) xanh - ((hanh doanh) OR (hang doanh)) luan nang song danh toan ban*.
