Perhaps you should try some spelling variations:
models transport » modal transport, modern transport, nodes transport
transport cote » transport code, transport costs, transport notes
data transfer » cash transfer, heat transfer
a transfer » cash transfer, heat transfer, land transfer
bias der » bias des, bias over, das der
cote _ » coate _, note _, vote _
a ao » a a, a co, a o
area » areas

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: (( area based models transport cote _ ) OR ( bias der ((a transfer) OR (data transfer)) a ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( area based models transport cote _ ) or ( bias der ((a transfer) OR (data transfer)) a ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( area based models transport cote _ ) or ( bias der ((a transfer) OR (data transfer)) a ao ))*.
