Perhaps you should try some spelling variations:
tham thuc » nham thuc, pham thuc, tam thuc
cua triet » cua viet, su triet, va triet
thuc gia » thuc giai, thue gia, thuc dia
thanh va » thanh van, thanh ha, thanh ve
nang xa » nang x, lang xa, nang ma
va tham » van tham, va cham, va thanh
hanh va » hang va, hanh vi
su sac » su sach, su cac
su xac » pu xac, su cac

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

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