Perhaps you should try some spelling variations:
cua triet » cua viet, su triet, va triet
hieu vien » hieu hien, hieu viec, thieu nien
vien dai » hien dai
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
dai loc » dai luoc, dai hoc
nang xa » nang x, nang ma, mang xa
lang xa » lang ha, dang xay, lang van
sac ky » cac ky, sai ky
loc va » hoc va, luc va
su sac » su sach, su cac, su xac

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

• Performing a fuzzy search may retrieve terms with similar spellings: su sac ky ((nang xa) or (lang xa)) hoi. hieu vien dai loc va ((thanh vi) OR (thanh ve)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ky ((nang xa) OR (lang xa)) hoi. hieu vien dai loc va ((thanh vi) OR (thanh ve)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ky ((nang xa) or (lang xa)) hoi. hieu vien dai loc va ((thanh vi) OR (thanh ve)) cua triet*".
