Perhaps you should try some spelling variations:
cua triet » cua viet, su triet
va triet » va thiet, va trien, ve triet
hieu van » hieu va, thien van, lieu va
thanh vi » hanh vi, thanh va, thanh ve
va thanh » gia thanh, ban thanh, va tinh
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va
y nang » ky nang, ly nang, v nang
xuc va » duc va, tuc va, luc va
sinh y » sinh ly

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sinh y nang xa hoi. ((hieu ve) or (hieu van)) cam xuc va thanh vi ((cua triet) OR (va triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh y nang xa hoi. ((hieu ve) OR (hieu van)) cam xuc va thanh vi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh y nang xa hoi. ((hieu ve) or (hieu van)) cam xuc va thanh vi ((cua triet) OR (va triet))".
• Adding a wildcard symbol may retrieve word variants: hoc sinh y nang xa hoi. ((hieu ve) or (hieu van)) cam xuc va thanh vi ((cua triet) OR (va triet))*.
