Perhaps you should try some spelling variations:
ideas transfer » ideas transform, ideas transarea, ideas transport
data transfers » water transfers, cash transfers, land transfers
data transfer » cash transfer, heat transfer
transfer der » transfer fees, transfer _
der marc » der mark, der markt, der marel
runs 2.1 » runs 5.1, runs 9.1, eucs 2.1
field 4 » field _, field 3

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 _ ideas transfer der marc ) OR ( runs 2.1 ((data transfers) OR (data transfer)) field 4 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis _ ideas transfer der marc ) or ( runs 2.1 ((data transfers) OR (data transfer)) field 4 ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis _ ideas transfer der marc ) or ( runs 2.1 ((data transfers) OR (data transfer)) field 4 ))*.
