Perhaps you should try some spelling variations:
transfer across » transfer costs, transfer accounts
data transfer » cash transfer, heat transfer
transfers ai » transfers i, transfers bei, transfers dau
across case » across caste, cross case, across age
luis a » luis f, luis c
a arms » _ arms, a arm
luis 1 » luis f, luis c, luis e
1 data » 2.1 data, 3.1 data, 4.1 data

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 arms transfers ai (marx OR mark) ) OR ( luis 1 data transfer across case ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis a arms transfers ai (marx or mark) ) or ( luis 1 data transfer across case ))*.
