Perhaps you should try some spelling variations:
transport code » transport mode, transport modes, transport model
sea transport » road transport, bus transport
12 transfer » 2 transfer, 1.3 transfer, 2.2 transfer
1 transfer » 1 transfert, a transfer, 2 transfer
areas cnn » areas can, areas co
bias time » bias die, das time, his time
3 do » _ do, 3 d, 1 do

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 cnn sea transport code _ ) OR ( bias time ((1 transfer) OR (12 transfer)) 3 do ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( areas cnn sea transport code _ ) or ( bias time ((1 transfer) OR (12 transfer)) 3 do ))~".
• Adding a wildcard symbol may retrieve word variants: (( areas cnn sea transport code _ ) or ( bias time ((1 transfer) OR (12 transfer)) 3 do ))*.
