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 4, transfer der
transfer 3 » transfer _, transfer 4, transfer 3.2
bias der » bias des, bias over, das der
der heat » der heimat, der heydt, der heute
cote _ » coate _, note _, vote _
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 ( bias der heat ((transfer a) OR (transfer 3)) ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( area based models transport cote _ ) or ( bias der heat ((transfer a) OR (transfer 3)) ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( area based models transport cote _ ) or ( bias der heat ((transfer a) OR (transfer 3)) ao ))*.
