Perhaps you should try some spelling variations:
hanh le » thanh le, hanh ve, hanh de
va hanh » van hanh, va thanh, va danh
cam loc » cam lo
hieu va » lieu va
cua tre » cua te, cuu tre, cua triet
nang xa » nang x, lang xa, nang ma
sach v » sach va, sach y, sach vay
sach 2 » sach y
loc va » hoc va, luc va
le cua » ly cua

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

• Performing a fuzzy search may retrieve terms with similar spellings: toc ((sach v) or (sach 2)) nang xa hoi. ((hieu va) OR (hieu qua)) cam loc va hanh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach v) OR (sach 2)) nang xa hoi. ((hieu va) OR (hieu qua)) cam loc va hanh le cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach v) or (sach 2)) nang xa hoi. ((hieu va) OR (hieu qua)) cam loc va hanh le cua tre*".
