Perhaps you should try some spelling variations:
transfer costs » transport costs, transfer amounts
data transfer » cash transfer
den transfer » gene transfer, land transfer, bank transfer
bei carl » wei carol, iii carl
luis a » luis f, luis c
luis i » luis f, luis c, luis e
i data » ii data, ai data, 2 data

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 a ((den transfer) OR (heat transfer)) bei carl ) OR ( luis i data transfer costs _ ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a ((den transfer) OR (heat transfer)) bei carl ) or ( luis i data transfer costs _ ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a ((den transfer) OR (heat transfer)) bei carl ) or ( luis i data transfer costs _ ))*.
