Perhaps you should try some spelling variations:
su triet » su viet, su tien, ve triet
thanh ve » hanh ve, thanh va, thanh vien
thanh vi » hanh vi, thanh va, nhanh vi
xuc ban » duc ban, cuc ban, quoc ban
hieu va » lieu va, hieu qua
nang xa » nang x, lang xa, nang ma
cao xuc » cam xuc, cao duc, cao suc
va cao » va cac, va co, va dao
sach v » sach va, sach 2, sach vay

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

• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach v) or (sach y)) nang xa hoi. hieu va cao xuc ban ((thanh vi) OR (thanh ve)) su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach v) OR (sach y)) nang xa hoi. hieu va cao xuc ban ((thanh vi) OR (thanh ve)) su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach v) or (sach y)) nang xa hoi. hieu va cao xuc ban ((thanh vi) OR (thanh ve)) su triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach v) or (sach y)) nang xa hoi. hieu va cao xuc ban ((thanh vi) OR (thanh ve)) su triet*.
