Perhaps you should try some spelling variations:
pham cuc » pham chuc, pham duc, pham cua
tu sach » thu sach, su sach, te sach
xang xa » lang xa, mang xa, dang xay
hieu va » lieu va, hieu qua
va pham » van pham, va phat, va phap
cuc ban » cua ban, cac ban, cuu ban
ban anh » ban hanh, ban banh, ban danh
ang xa » lang xa, mang xa, dang xay
da cua » dai cua, day cua, dan cua
d cua » de cua, do cua, di cua

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 y ((xang xa) OR (ang xa)) hoi. hieu va pham cuc ban anh ((d cua) OR (da cua)) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((xang xa) OR (ang xa)) hoi. hieu va pham cuc ban anh ((d cua) or (da cua)) tre~".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((xang xa) OR (ang xa)) hoi. hieu va pham cuc ban anh ((d cua) or (da cua)) tre*.
