Perhaps you should try some spelling variations:
nuoc sach » nguoi sach, hoc sach, cuoc cach
thien van » thi van
thu sach » tu sach, thuat sach, thuoc sach
cua viet » hoa viet, cua vat, cua dieu
tinh lap » trinh lap, tinh lao, dinh lap
va tinh » may tinh
ban xuc » ban xu, ban duoc, ban phuc
nang xa » nang x, lang xa, nang ma
ca viet » va viet, co viet, hoa viet
xuc va » duc va, tuc va, luc va
y nang » ky nang, ly nang, v nang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (nuoc sach)) y nang xa hoi. thien van ban xuc va tinh lap ((cua viet) OR (ca viet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (nuoc sach)) y nang xa hoi. thien van ban xuc va tinh lap ((cua viet) OR (ca viet))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (nuoc sach)) y nang xa hoi. thien van ban xuc va tinh lap ((cua viet) OR (ca viet))*".
