Perhaps you should try some spelling variations:
thanh vien » nhan vien, thanh van
cua triet » cua viet, su triet, va triet
cac thuc » cach thuc, can thuc, cay thuc
so sach » so sanh, bo sach, co sach
hieu va » lieu va, hieu qua
cac thu » cach thuc, cac thoi
cua tre » cua te, cuu tre, dua tren
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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 y nang x hoi. hieu va ((cac thuc) OR (cac thu)) gia thanh vien ((cua tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach y nang x hoi. hieu va ((cac thuc) OR (cac thu)) gia thanh vien ((cua tre) OR (cua triet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach y nang x hoi. hieu va ((cac thuc) OR (cac thu)) gia thanh vien ((cua tre) or (cua triet))*".
