Perhaps you should try some spelling variations:

thanh dat » thanh san, thanh hai, thanh van
thanh dai » thanh hai, thanh tai, thanh oai
hieu van » hieu va, thien van, lieu va
hac xuc » chat xuc
sach tu » sach thu, cach tu, sach uu
lang xa » lang ha, dang xay, lang van
sach ty » sach y, sach thu, xach tay
van hac » van hoc, van ha, van hai
xuc va » duc va, tuc va, luc va

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 tu) or (sach ty)) lang xa hoi. hieu van hac xuc va ((thanh dai) OR (thanh dat)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach ty)) lang xa hoi. hieu van hac xuc va ((thanh dai) OR (thanh dat)) cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) or (sach ty)) lang xa hoi. hieu van hac xuc va ((thanh dai) OR (thanh dat)) cua triet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) or (sach ty)) lang xa hoi. hieu van hac xuc va ((thanh dai) OR (thanh dat)) cua triet*.
