Perhaps you should try some spelling variations:
giai tuong » giai thuong, giai phong, dai tuong
gian muong » giang duong, gian trong
sach hinh » sach kinh, sach danh, sach han
gia tuong » gia cong, gia tang, va tuong
gia cuong » gia cong, gia dung
doi gian » don gian, doi giam, toi gian
tinh doi » trinh doc, trinh do, tinh hoc
bai giai » bai giang, va giai, dan giai
hinh bai » hinh tai, hinh thai, tinh bac
hinh bi » hinh ai, hinh tai, chinh vi
te sach » toc sach
su sac » su sach, su cac
su xac » pu xac, su cac

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: "((((\"te sach hinh bi ((gia tuong) OR (gia cuong))\") or (\"te sach hinh bai giai tuong\"))) or (\"((su sac) OR (su xac)) tinh doi gian muong\"))*".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((((\\"te sach hinh bi ((gia tuong) OR (gia cuong))\\") or (\\"te sach hinh bai giai tuong\\"))) or (\\"((su sac) or (su xac)) tinh doi gian muong\\"))*\"".
• Removing quotes may allow a broader search: (((( te sach hinh bi ((gia tuong) OR (gia cuong)) ) or ( te sach hinh bai giai tuong ))) or ( ((su sac) or (su xac)) tinh doi gian muong ))*.
