Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
chu bang » thu bang, chuc nang, chu quang
thi nang » thi cong, ki nang, thi hanh
hanh dai » hanh tai, hanh dao, vanh dai
va hanh » van hanh, va thanh, va danh
te sach » toc sach
ve chao » ve chat, ve cham, ve cho
hieu ve » hieu va, hieu van
xu va » xu van, tu va, su va

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

• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((chu bang) or (thi nang)) xa hoi. hieu ve chao xu va hanh dai ((cua triet) OR (su triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((chu bang) OR (thi nang)) xa hoi. hieu ve chao xu va hanh dai ((cua triet) OR (su triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((chu bang) or (thi nang)) xa hoi. hieu ve chao xu va hanh dai ((cua triet) OR (su triet))".
• Adding a wildcard symbol may retrieve word variants: te sach ((chu bang) or (thi nang)) xa hoi. hieu ve chao xu va hanh dai ((cua triet) OR (su triet))*.
