Perhaps you should try some spelling variations:
transfer model » transfer models, transfer money, transfer der
sea transport » road transport, bus transport
transport de » transport der, transport des, transport du
imf data » imf's data, dlf data, rdf data
de marx » oder marx, de maria, bei marx
luis a » luis f, luis c
1 data » 2.1 data, 3.1 data, 4.1 data
a sea » _ sea, a set

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: (( luis a sea transport de marx ) OR ( luis ((imf data) OR (1 data)) transfer model _ ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a sea transport de marx ) or ( luis ((imf data) or (1 data)) transfer model _ ))*.
