Perhaps you should try some spelling variations:
transport cote » transport code, transport notes, transport cost
areas based » area based, areas case
a transfer » cash transfer, heat transfer, data transfer
transfer a » transfer _, transfer 3, transfer 4
bias der » bias des, bias over, das der
der a » der _, der e
a co » _ co

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