Perhaps you should try some spelling variations:
tinh vien » sinh vien, tinh dien, tinh viet
cua triet » cua viet
su triet » su viet, su tien, ve triet
va triet » va thiet, va trien, ve triet
nhan luc » nang luc
va tinh » may tinh
va nhan » van nhan, ca nhan, va phan
hieu va » lieu va, hieu qua
cao hoi » cau hoi, co hoi, cao hoc
sac ky » cac ky, sai ky
luc va » duc va, tuc va, loc va
tu sac » tu sach, tu cac, tu san

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 cao hoi. hieu va nhan luc va tinh vien ((((cua triet) OR (va triet))) or (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang cao hoi. hieu va nhan luc va tinh vien ((((cua triet) OR (va triet))) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang cao hoi. hieu va nhan luc va tinh vien ((((cua triet) OR (va triet))) or (su triet))".
• Adding a wildcard symbol may retrieve word variants: tu sac ky nang cao hoi. hieu va nhan luc va tinh vien ((((cua triet) OR (va triet))) or (su triet))*.
