Perhaps you should try some spelling variations:
nhieu viec » hieu viec, nhien viet
tu sach » thu sach, su sach, te sach
lang xa » lang ha, dang xay, lang van
thuc va » thuc vat, thuc dan, thuc day
tinh de » tinh da, sinh de, tinh he
cua tre » cua te, cuu tre, cua triet
y lang » o lang, _ lang, tay lang
xuc va » duc va, tuc va, xac va
luc va » duc va, tuc va, loc va
de cua » le cua, te cua, dieu cua

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 y lang xa hoi. nhieu viec cua ((((xuc va) OR (luc va))) or (thuc va)) tinh de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. nhieu viec cua ((((xuc va) OR (luc va))) OR (thuc va)) tinh de cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. nhieu viec cua ((((xuc va) OR (luc va))) or (thuc va)) tinh de cua tre*".
