Perhaps you should try some spelling variations:
hoc nhanh » hoc phan
cau phan » chau phan, cuu phan, cac phan
phan van » pham van, thanh van, luan van
su sach » so sach, vu sach
sach do » sach dao, sach doi, sach de
cuu mon » cuu mo, cuu mot, cuu cong
hoi cau » hoi chu, hoc cau, hoa cau
do dap » doi dap, do dai, do dac
hoc xa » hoc ma

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: su sach do dap, nghien cuu mon ((hoc nganh) OR (hoc nhanh)) hoa hoc xa hoi cau phan van~.
• Adding a wildcard symbol may retrieve word variants: su sach do dap, nghien cuu mon ((hoc nganh) or (hoc nhanh)) hoa hoc xa hoi cau phan van*.
