Perhaps you should try some spelling variations:
nhung thoi » phung thi, nhung loi, nhung tri
nhung thi » phung thi, nhung tri, nhung chi
nhung bi » nhung bai, nhung gi
quan van » luan van, quan va, quan luan
noi dung » hoc dung
hoc mon » hoc moi, hoc mot, hoc cong
hoc mo » hoc moi, hoc mot, hoc ma

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((((nhung thoi) or (nhung bi))) or (nhung thi)) quan van. noi dung ((hoc mo) or (hoc mon))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((nhung thoi) OR (nhung bi))) OR (nhung thi)) quan van. noi dung ((hoc mo) OR (hoc mon)).
• Adding a wildcard symbol may retrieve word variants: ((((nhung thoi) or (nhung bi))) or (nhung thi)) quan van. noi dung ((hoc mo) or (hoc mon))*.
