Perhaps you should try some spelling variations:
transformer spanned » transformer based
dc transformer » _ transformer, 3 transformer, a transformer
spanned across » shared across, space across
transfer bei » transfer beim, transfers bei, transfer der
ende dc » ende der, ende des, ende den
a net » a new, a neo
_ net » _ new
bis » bias
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: (( bis ende dc transformer spanned across ) OR ( luis ((a net) OR (_ net)) transfer bei marx ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( bis ende dc transformer spanned across ) or ( luis ((a net) OR (_ net)) transfer bei marx ))~".
• Adding a wildcard symbol may retrieve word variants: (( bis ende dc transformer spanned across ) or ( luis ((a net) OR (_ net)) transfer bei marx ))*.
