Perhaps you should try some spelling variations:
rail transport » road transport
transport cost » transport costs
far transfer » a transfer, gas transfer, water transfer
transfer a » transfer _, transfer 3, transfer 4
areas un » areas can, areas _, areas a
bias der » bias des, bias over, das der
der far » der fan, der fahrt, der farce
a do » a dot, _ do, a d

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 un rail transport cost _ ) OR ( bias der far transfer a do ))~.
• Adding a wildcard symbol may retrieve word variants: (( areas un rail transport cost _ ) or ( bias der far transfer a do ))*.
