Perhaps you should try some spelling variations:
models transport » modal transport, modern transport, nodes transport
transport cote » transport code, transport costs, transport notes
transfer a » transfer _, transfer 3, transfer 4
der heat » der heimat, der heydt, der heute
das der » dass der, das dorf, das drei
cote _ » coate _, note _, vote _
a ao » a a, a co, a o
area » areas

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: (( area based models transport cote _ ) OR ( das der heat transfer a ao ))~.
• Adding a wildcard symbol may retrieve word variants: (( area based models transport cote _ ) or ( das der heat transfer a ao ))*.
