Perhaps you should try some spelling variations:
transformer based » transformer les, transport based, transformation based
dc transformer » _ transformer, 3 transformer, a transformer
based access » basic access, basin access, case access
de transfert » le transfert, de transport, de transporte
transfert de » transfer der, transfert et, transfer _
bias ende » bis ende, bias index, das ende
ende dc » ende der, ende des, ende den
luis de » luis e
de cao » de caso, de cabo, de capo
de de » e de, de ce, de se

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 dc transformer based access ) OR ( luis de de transfert de cao ))~.
• Adding a wildcard symbol may retrieve word variants: (( bias ende dc transformer based access ) or ( luis de de transfert de cao ))*.
