Perhaps you should try some spelling variations:
der transfers » des transfers, der transfer, net transfers
transfer gene » transfer gender, transfer agent, transfer fee
transfers ai » transfers i, transfers bei, transfers dau
gene case » genk case, gender case, mene caste
imf data » imf's data, dlf data
rdf data » dlf data
ai marc » bei marc
luis a » luis f, luis c
a der » _ der, 2 der, 3 der

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 der transfers ai marc ) OR ( luis ((imf data) OR (rdf data)) transfer gene case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis a der transfers ai marc ) or ( luis ((imf data) OR (rdf data)) transfer gene case ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis a der transfers ai marc ) or ( luis ((imf data) OR (rdf data)) transfer gene case ))*.
