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
hieu va » lieu va, hieu qua
so sach » so sanh, co sach, hoc sach
nang xa » nang x, lang xa, nang ma
ty nang » ky nang, ty xang, ty hang
bo sach » co sach, hoc sach
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) OR (bo sach)) ty nang xa 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) OR (bo sach)) ty nang xa 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) OR (bo sach)) ty nang xa hoi. hieu va can thuc va ((thanh vi) or (hanh vi)) cua triet".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (bo sach)) ty nang xa hoi. hieu va can thuc va ((thanh vi) or (hanh vi)) cua triet*.
