Perhaps you should try some spelling variations:
nghien thu » nghiem thuc, nghiep thuc, nghien cuu
hoc nhanh » hoc phan
khoa hoc » hoa hoc
nhan van » nhan dan, nhan va, phan van
hoc hoc » hoc hoa, toc hoc, hoc hoi
va nhan » van nhan, ca nhan, va phan
ma hoi » mai hoi, xa hoi, ma hoa

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: "te hoc hoc tap, nghien thu cong ((hoc nganh) OR (hoc nhanh)) khoa hoc ma hoi va nhan van~".
• Adding a wildcard symbol may retrieve word variants: te hoc hoc tap, nghien thu cong ((hoc nganh) OR (hoc nhanh)) khoa hoc ma hoi va nhan van*.
