Perhaps you should try some spelling variations:
land transport » road transport
langues key » langues de, langues et
transport a » transport _, transport data
guias der » guias de, guia de, bias der
costs la » costs a, costs land, costs _
der land » der lander, der landes, der lange
a a » a la

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: (( langues key bus transport costs la ) OR ( guias der land transport a a ))~.
• Adding a wildcard symbol may retrieve word variants: (( langues key bus transport costs la ) or ( guias der land transport a a ))*.
