Perhaps you should try some spelling variations:
cua triet » cua viet, va triet
su triet » su viet, su tien, ve triet
hanh lai » hanh lam, hanh tai, thanh lap
va hanh » van hanh, va thanh, va danh
sach ky » sac ky, sach ty, sach kem
hieu ve » hieu va, hieu van
nang xa » nang x, lang xa, nang ma
xuc va » duc va, tuc va, luc va
ve cam » ve cham, ve cac, va cam

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

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