Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
cau treo » cau theo, cau tren, cau triet
viec cac » vien cac, viec cua, viec lam
van danh » van doanh, van anh, van hanh
cuu tre » cua tre, cau tren
danh va » doanh va, hanh va, anh va
sach ty » sach tu, sach thu, xach tay
nang xa » nang x, lang xa, nang ma
lo van » le van, vo van, so van
cac lo » cac lop, cac co, cac bo

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

• Performing a fuzzy search may retrieve terms with similar spellings: te ((sach ty) or (sach y)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ty) OR (sach y)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ty) or (sach y)) nang xa hoi. nhieu viec cac lo van danh va ((cuu tre) OR (cau treo))*".
