Perhaps you should try some spelling variations:
transport data » transport demand
sea transport » road transport, bus transport
transfer a » transfer _, transfer 3, transfer der
transfer 4 » transfer _, transfer 3, transfer der
areas own » areas can
bias time » bias die, das time, his time
own sea » own ses, own seed, own real
time a » time _

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 own sea transport data _ ) OR ( bias time a ((transfer a) OR (transfer 4)) do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas own sea transport data _ ) or ( bias time a ((transfer a) OR (transfer 4)) do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas own sea transport data _ ) or ( bias time a ((transfer a) OR (transfer 4)) do ))*.
