Perhaps you should try some spelling variations:

hoc sach » hoc sinh, hoc cac, hoc anh
cham luc » cham soc, nhan luc, cham cuu
tinh bai » tinh bac, tinh hai, hinh bai
nang xa » nang x, lang xa, nang ma
hieu ve » hieu va, hieu van
luc may » truc may, phuc may
cua tre » cua te, cuu tre, dua tren
y nang » ky nang, ly nang, v nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: hoc sach y nang xa hoi. ((hieu ve) or (lieu va)) cham luc may tinh bai ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sach y nang xa hoi. ((hieu ve) OR (lieu va)) cham luc may tinh bai ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sach y nang xa hoi. ((hieu ve) or (lieu va)) cham luc may tinh bai ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: hoc sach y nang xa hoi. ((hieu ve) or (lieu va)) cham luc may tinh bai ((cua tre) OR (cua triet))*.
