Perhaps you should try some spelling variations:
ve triet » va trien, su triet
dang xay » dang van, van xay
hanh ve » hanh vi, hanh va, hanh kem
va hanh » van hanh, va thanh, va danh
sach ky » sac ky, sach y, sach ty
te sach » toc sach
lang xa » lang ha, lang van
ve cac » va cac, vien cac
xuc va » duc va, tuc va, luc va
ve cam » ve cham, va cam, ve cai
ve ve » de ve, va ve, ke ve

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 ky ((lang xa) or (dang xay)) hoi. hieu ((ve cam) OR (ve cac)) xuc va hanh ve ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((lang xa) OR (dang xay)) hoi. hieu ((ve cam) OR (ve cac)) xuc va hanh ve ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((lang xa) or (dang xay)) hoi. hieu ((ve cam) OR (ve cac)) xuc va hanh ve ve triet".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((lang xa) or (dang xay)) hoi. hieu ((ve cam) OR (ve cac)) xuc va hanh ve ve triet*.
