Perhaps you should try some spelling variations:
models transport » modal transport, modern transport, nodes transport
transport notes » transport rates, transport needs, transport noise
areas based » area based, areas case
transfer a » transfer _, transfer 4, transfer der
transfer 3 » transfer _, transfer 4, transfer 3.2
das der » dass der, das dorf, das drei
der e » der eg, der _

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: (( areas based models transport notes _ ) OR ( das der e ((transfer a) OR (transfer 3)) ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas based models transport notes _ ) or ( das der e ((transfer a) OR (transfer 3)) ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas based models transport notes _ ) or ( das der e ((transfer a) OR (transfer 3)) ao ))*.
