Perhaps you should try some spelling variations:
transport data » transport demand
sea transport » road transport, bus transport
a transfer » cash transfer, heat transfer, data transfer
transfer a » transfer _, transfer 3, transfer 4
areas own » areas can
bias time » das time, his time
bias die » bias due, bias der, bias des
own sea » own ses, own seed, own real
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 own sea transport data _ ) OR ( ((bias time) OR (bias die)) a transfer a do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas own sea transport data _ ) or ( ((bias time) OR (bias die)) a transfer a do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas own sea transport data _ ) or ( ((bias time) OR (bias die)) a transfer a do ))*.
