Perhaps you should try some spelling variations:
tu sach » thu sach, su sach, tu cach
thi cuu » thi cuc, thi huu, thi cu
dao thi » do thi, dan thi, dang thi
cac xuc » cam xuc, cac nuoc, chat xuc
nang ma » tang ma, sang ma, nang cao
te sach » toc sach
nang xa » nang x, lang xa, mang xa
cuu tre » cua tre, cau tren, cau treo
xuc va » duc va, tuc va, luc va
va dao » ca dao

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: ((tu sach) OR (te sach)) y ((nang xa) OR (nang ma)) hoi. lieu va cac xuc va dao thi cuu tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu sach) or (te sach)) y ((nang xa) OR (nang ma)) hoi. lieu va cac xuc va dao thi cuu tre~".
• Adding a wildcard symbol may retrieve word variants: ((tu sach) or (te sach)) y ((nang xa) OR (nang ma)) hoi. lieu va cac xuc va dao thi cuu tre*.
