Perhaps you should try some spelling variations:
hoc nganh » hoc nhanh
soc nganh » hoc nhanh, cac nganh, moi nganh
thu sach » tu sach, thuat sach, thuoc sach
tan gian » tran gian, dan gian, van gian
cong hoc » dong hoc, cong hoa, cong coc
gian dan » gian lang
sach hoi » sach doi, sach moi, cach thoi
cuu long » cuu cong, cuu tong, cuu nang
hai tan » hai van, hai quan
hoi tai » hoc tai, hoi trac
hoc xa » hoc ma
xa hai » xa thai, xua hai, xa 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: thu sach hoi tai, nghien cuu long ((soc nganh) OR (hoc nganh)) cong hoc xa hai tan gian dan~.
• Adding a wildcard symbol may retrieve word variants: thu sach hoi tai, nghien cuu long ((soc nganh) or (hoc nganh)) cong hoc xa hai tan gian dan*.
