Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
viec cam » viec lam, viec cua, viec va
cua tre » cua te, cua triet, dua tren
tinh di » tinh doi, trinh di, tinh da
va tinh » may tinh
sach ky » sac ky, sach y, sach kem
tang xa » trang xa, tang ma, lang xa
sach ty » sach y, sach tu, sach thu
cuu tre » cau tren, cau treo
xuc va » duc va, tuc va, luc va

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach ty)) tang xa hoi. nhieu viec cam xuc va tinh di ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) tang xa hoi. nhieu viec cam xuc va tinh di ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) tang xa hoi. nhieu viec cam xuc va tinh di ((cua tre) or (cuu tre))*".
