Perhaps you should try some spelling variations:
giao nghiep » giai nghiep, khao nghiep
xay nghiem » xet nghiem, day nghiep, van nghiem
nghiep dai » nghiep tai, nghiep bai, nghiep va
nghiem su » nghiem xu, nghiem ngu, nghiem dau
tu sach » thu sach, su sach, tu cach
te sach » toc sach
su hoc » tu hoc, du hoc, so hoc

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 hoach xay nghiem su hoc ) OR ( ((tu sach) OR (te sach)) giao nghiep dai hoc ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thu hoach xay nghiem su hoc ) or ( ((tu sach) OR (te sach)) giao nghiep dai hoc ))~".
• Adding a wildcard symbol may retrieve word variants: (( thu hoach xay nghiem su hoc ) or ( ((tu sach) OR (te sach)) giao nghiep dai hoc ))*.
