Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » thanh va, thanh ve, nhanh vi
can thuc » dan thuc, van thuc, cay thuc
thuc va » thuc vat, thuc dan, thuc day
sach ty » sach y, sach tu, sach thu
so sach » so sanh, bo sach, co sach
hieu va » lieu va, hieu qua
nang xa » lang xa, nang ma, mang xa
va can » va chan, va cac, va cao

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

• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ((nang xa) OR (nang x)) hoi. hieu va can thuc va ((thanh vi) or (hanh vi)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((nang xa) OR (nang x)) hoi. hieu va can thuc va ((thanh vi) OR (hanh vi)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((nang xa) OR (nang x)) hoi. hieu va can thuc va ((thanh vi) or (hanh vi)) cua triet".
• Adding a wildcard symbol may retrieve word variants: so sach ty ((nang xa) OR (nang x)) hoi. hieu va can thuc va ((thanh vi) or (hanh vi)) cua triet*.
