Perhaps you should try some spelling variations:
hieu viec » nhieu viec, hieu ve, sieu viet
viec cac » vien cac, viec cua, viec lam
cua viet » ca viet, hoa viet, cua vat
ky lang » ky nang, ky dang, ky tang
lang xa » lang ha, dang xay, lang van
cac loc » cac lop, cac toc, cac hoc
loc may » hoc may, loc mau, loai may
tinh vi » trinh vi, tinh voi, tinh va
va viet » hoa viet, san viet, mai viet
so sac » so sach, so dac
sac ky » cac ky, sai ky

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: so sac ky lang xa hoi. hieu viec cac loc may tinh vi ((cua viet) OR (va viet))~.
• Adding a wildcard symbol may retrieve word variants: so sac ky lang xa hoi. hieu viec cac loc may tinh vi ((cua viet) or (va viet))*.
