Perhaps you should try some spelling variations:
ve triet » va trien, su triet
dang xay » dang van, van xay
nam thuc » nam thuoc, am thuc, nam thu
dau dai » dat dai, sau dai, dau da
thuc va » thuc vat, thuc dan, thuc day
hieu ly » hieu ky, lieu ly, dieu ly
hoc anh » hoc nganh, hoc nhanh, ngoc anh
lang xa » lang ha, lang van
nang xa » nang x, nang ma, mang xa
va dau » va dao
dai ve » dap ve, dau ve, dai va
anh y » hanh y, anh d, anh _

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc anh y ((nang xa) or (((lang xa) OR (dang xay)))) hoi. hieu ly nam thuc va dau dai ve triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc anh y ((nang xa) OR (((lang xa) OR (dang xay)))) hoi. hieu ly nam thuc va dau dai ve triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc anh y ((nang xa) or (((lang xa) OR (dang xay)))) hoi. hieu ly nam thuc va dau dai ve triet".
• Adding a wildcard symbol may retrieve word variants: hoc anh y ((nang xa) or (((lang xa) OR (dang xay)))) hoi. hieu ly nam thuc va dau dai ve triet*.
