Perhaps you should try some spelling variations:
nganh dung » ngan dung, anh dung, nganh cong
hoc nganh » hoc nhanh
sach hoc » cach hoc, sach hoi, mach hoc
dung hoc » dong hoc, dung thuoc, trung hoc
phan van » pham van, thanh van, luan van
so sach » so sanh, bo sach, co sach
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
va phan » van phan, va phat, va phap
ma hoi » mai hoi, xa hoi, me hoi

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: so sach hoc tap, nghien cuu mon hoc nganh dung hoc ((ma hoi) OR (ma hoa)) va phan van~.
• Adding a wildcard symbol may retrieve word variants: so sach hoc tap, nghien cuu mon hoc nganh dung hoc ((ma hoi) or (ma hoa)) va phan van*.
