Perhaps you should try some spelling variations:
student transfer » student transfers, student teacher
transform lines » transforms lives, transform cities, transform ideas
lines across » links across, lives across, linkages across
transfer das » transfer cash, transfer case, transfer der
bias index » bios index
das makro » der makro
luis a » luis f
luis c » luis f

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: (( bias index _ transform lines across ) OR ( ((luis a) OR (luis c)) student transfer das makro ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bias index _ transform lines across ) or ( ((luis a) OR (luis c)) student transfer das makro ))~".
• Adding a wildcard symbol may retrieve word variants: (( bias index _ transform lines across ) or ( ((luis a) OR (luis c)) student transfer das makro ))*.
