Perhaps you should try some spelling variations:
nhan luc » nang luc
hieu van » hieu va, thien van, lieu va
hieu ve » hieu va
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach 2, sach vay
luc va » duc va, tuc va, loc va
va dao » ca dao
dao ve » bao ve, dap ve, dau ve
ve cua » le cua, de cua, te cua

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

• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach v) OR (sach y)) nang xa hoi. ((hieu ve) OR (hieu van)) nhan luc va dao ve cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach v) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu van)) nhan luc va dao ve cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach v) or (sach y)) nang xa hoi. ((hieu ve) OR (hieu van)) nhan luc va dao ve cua tre*.
