Perhaps you should try some spelling variations:
transfer bear » transfer der, transfer bei, transfer beim
transform fft » transform tvdft, transform cote, transform test
den transfer » gene transfer, heat transfer, data transfer
bear call » bear came, der call
rd1 data » 2.1 data, 3.1 data, 4.1 data
luis a » luis f, luis c
1 data » 2.1 data, 3.1 data, 4.1 data
a den » _ den, a der, a des

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 bear call ) OR ( luis ((1 data) OR (rd1 data)) transform fft _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a den transfer bear call ) or ( luis ((1 data) or (rd1 data)) transform fft _ ))*.
