Perhaps you should try some spelling variations:
transformer based » transformer les, transport based, transformation based
et transformer » et transformes, _ transformer, 3 transformer
based across » based access, shared across, varied across
net transfer » net transfers, heat transfer, money transfer
transfer bei » transfer beim, transfers bei, transfer der
bias ende » bis ende, bias index, das ende
bei mark » bei marx, bei marc, bei maria
ende et » ende der, ende des, etude et
luis e » luis f, luis a
luis c » luis f

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 et transformer based across ) OR ( ((luis e) OR (luis c)) net transfer bei mark ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bias ende et transformer based across ) or ( ((luis e) OR (luis c)) net transfer bei mark ))~".
• Adding a wildcard symbol may retrieve word variants: (( bias ende et transformer based across ) or ( ((luis e) OR (luis c)) net transfer bei mark ))*.
