Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
thanh ve » hanh ve, thanh va, thanh vien
va thanh » gia thanh, ban thanh, va tinh
cac thuc » cach thuc, cac thu, can thuc
nang xa » nang x, lang xa, nang ma
qua cac » cua cac
thuc va » thuc vat, thuc dan, thuc day
so sanh » do sanh
so sach » bo sach, co sach, hoc sach

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 (so sanh)) ky nang xa hoi. hieu qua cac thuc va thanh ve ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (so sanh)) ky nang xa hoi. hieu qua cac thuc va thanh ve ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) or (so sanh)) ky nang xa hoi. hieu qua cac thuc va thanh ve ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: ((so sach) or (so sanh)) ky nang xa hoi. hieu qua cac thuc va thanh ve ((cua triet) OR (va triet))*.
