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
e transfer » ee transfer, 2 transfer, 1 transfer
a transfer » cash transfer, heat transfer, data transfer
das der » dass der, das dorf, das drei
a ao » a a, a co, a o

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