Perhaps you should try some spelling variations:
transform tvdft » transform fft, transform test
transfer bear » transfer der, transfer bei, transfer beim
transfer test » transfer west, transform test, transfer cost
der transfer » der transfers, den transfer, peer transfer
bear call » bear came, der call
luis rdf » luis de
rdf data » dlf data, imf data
f der » _ der, 2 der, 3 der

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 f der transfer bear call ) OR ( luis rdf data ((transfer test) OR (transform tvdft)) _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis f der transfer bear call ) or ( luis rdf data ((transfer test) or (transform tvdft)) _ ))*.
