Perhaps you should try some spelling variations:
doc sach » hoc sach, toc sach, nuoc sach
dinh tai » dinh toai, dinh tri, dinh thi
van dinh » van minh, van dich, va dinh
toc cham » toc thai
tuc cham » tu cham, phuc cham, thuc chan
xuc van » duc van, luc van, vuc van
lang xa » lang ha, dang xay, lang van
cua tre » cuu tre, cua triet, dua tren
y lang » o lang, _ lang, tay lang
cua te » cua tu

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

• Performing a fuzzy search may retrieve terms with similar spellings: doc sach y lang xa hoi. hieu ((tuc cham) or (toc cham)) xuc van dinh tai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach y lang xa hoi. hieu ((tuc cham) OR (toc cham)) xuc van dinh tai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach y lang xa hoi. hieu ((tuc cham) or (toc cham)) xuc van dinh tai ((cua tre) OR (cua te))*".
