Perhaps you should try some spelling variations:
tinh vien » sinh vien, tinh dien, tinh viet
thien van » thi van
cua triet » cua viet, su triet, va triet
hieu van » hieu va, lieu va, hieu ve
vien cua » viec cua, dien cua, tien cua
nang xa » nang x, lang xa, nang ma
nam xuc » cam xuc, nam xua, nam thuc
xuc may » xuc hay, truc may, phuc may
tu sac » tu sach, tu san, tu bac

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