Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu ve » hieu va, hieu van
va dung » van dung, va duong, vat dung
so sach » so sanh, bo sach, co sach
ky dang » ky nang, ky danh

dung co » dung cho, dung cong, dung cua
so sac » so dac
dam tu » nam tu, cam tu, tam tu
ve dam » ven dam, ke dam, va dam
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((so sac) OR (so sach)) ky dang xa hoi. hieu ve dam tu va dung co ((cua triet) or (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sac) OR (so sach)) ky dang xa hoi. hieu ve dam tu va dung co ((cua triet) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sac) OR (so sach)) ky dang xa hoi. hieu ve dam tu va dung co ((cua triet) or (cua te))".
• Adding a wildcard symbol may retrieve word variants: ((so sac) OR (so sach)) ky dang xa hoi. hieu ve dam tu va dung co ((cua triet) or (cua te))*.
