Perhaps you should try some spelling variations:
hoc nhanh » hoc phan
sach hoc » cach hoc, sach hoi, mach hoc
khoa hoc » hoa hoc
van luan » van quan, van tuan, von luan
tu sach » thu sach, su sach, te sach
cuu mon » cuu mo, cuu mot, cuu cong
hoi van » hoi va, hoi dan, hai van
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: "tu sach hoc tap, nghien cuu mon ((hoc nganh) OR (hoc nhanh)) khoa hoc ma hoi van luan van~".
• Adding a wildcard symbol may retrieve word variants: tu sach hoc tap, nghien cuu mon ((hoc nganh) OR (hoc nhanh)) khoa hoc ma hoi van luan van*.
