Perhaps you should try some spelling variations:
nganh khong » nganh cong, nhanh chong, nganh nong
hoc nganh » hoc nhanh
khong hoc » khung hoc, thong hoc, khong thuoc
sach hoi » sach doi, cach thoi, hoach hoi
sach moi » sach doi, bach mai, sach bai
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
va phan » van phan, va phat, va phap
phan va » phan van, nhan va, han va
hoc xa » hoc ma

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach hoi) OR (sach moi)) tap, nghien cuu mon hoc nganh khong hoc xa hoi va phan va~".
• Adding a wildcard symbol may retrieve word variants: su ((sach hoi) OR (sach moi)) tap, nghien cuu mon hoc nganh khong hoc xa hoi va phan va*.
