Perhaps you should try some spelling variations:
human transport » urban transport, ocean transport, main transport
rural transport » road transport, rail transport
data transfer » cash transfer, heat transfer
transfer our » transfert pour, transfer der, transfer auf
aus dem » aus der
luis a » luis f, luis c
our a » our _, sur a
mass » maps

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: (( aus dem ((human transport) OR (rural transport)) air mass ) OR ( luis a data transfer our a ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( aus dem ((human transport) OR (rural transport)) air mass ) or ( luis a data transfer our a ))~".
• Adding a wildcard symbol may retrieve word variants: (( aus dem ((human transport) OR (rural transport)) air mass ) or ( luis a data transfer our a ))*.
