Perhaps you should try some spelling variations:
cua triet » su triet, va triet
cua viet » ca viet, hoa viet, cua vat
hieu ve » hieu va, hieu van
cam tuc » cam xuc, cam tu, nam thuc
xa dung » xay dung, xa dong, va dung
dung co » dung cho, dung cong, dung cua
bach y » sach y
y nang » ky nang, ly nang, v nang
x hoi » xa hoi, o hoi, x ho

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

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