Perhaps you should try some spelling variations:
der transformer » dc transformer, se transformer, der transferamter
transformer 1 » transformer _, transformed _
transfers bei » transfer bei, transfer beim, transfers ai
bias ende » bis ende, bias index, das ende
1 across » 19 across, eu across, ct across
luis e » luis f, luis a
luis c » luis f
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: (( bias ende der transformer 1 across ) OR ( ((luis e) OR (luis c)) _ transfers bei marx ))~.
• Adding a wildcard symbol may retrieve word variants: (( bias ende der transformer 1 across ) or ( ((luis e) or (luis c)) _ transfers bei marx ))*.
