Perhaps you should try some spelling variations:
nganh khoa » nganh hoa, nganh khong, anh khoa
doanh khoa » toan khoa
cach hoi » cach thoi, cach noi, cach hoc
nhan van » nhan dan, nhan va, phan van
su cach » su sach, tu cach, su cac
cuu mon » cuu mo, cuu mot, cuu cong
mon hoc » toan hoc, dong hoc
va nhan » van nhan, ca nhan, va phan
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 cach hoi dap, nghien cuu mon hoc ((nganh khoa) OR (doanh khoa)) hoc xa hoi va nhan van~".
• Adding a wildcard symbol may retrieve word variants: su cach hoi dap, nghien cuu mon hoc ((nganh khoa) OR (doanh khoa)) hoc xa hoi va nhan van*.
