Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
nham thuc » nam thuc, nham thu, pham thuc
nhan thuc » nhan luc, dan thuc, toan thuc
nang may » mang may, nang ma, bang may
may hoi » may thoi, tay hoi, mai hoi
hieu va » lieu va, hieu qua
hanh va » hang va
tu sac » tu sach, tu cac, tu san
sac ky » cac ky, sai ky

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

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