Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
thanh vi » hanh vi, thanh va, thanh ve
thuc va » thuc vat, thuc dan, thuc day
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
ve cam » ve cham, ve cac, va cam
sac ky » sai ky
tuc va » truc va, tuc xa, duc va
vi cua » vai cua, di cua

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

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