Perhaps you should try some spelling variations:
transform health » transforming health, reform health
den transfer » gene transfer, heat transfer, data transfer
transfer bei » transfer beim, transfers bei, transfer der
dlf data » imf data
rdf data » imf data
health 1 » health _, health a
marx » mark, mary, marc

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: (( luis _ den transfer bei marx ) OR ( luis ((dlf data) OR (rdf data)) transform health 1 ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis _ den transfer bei marx ) or ( luis ((dlf data) or (rdf data)) transform health 1 ))*.
