Perhaps you should try some spelling variations:
transfer risks » transfer risk
data transfer » cash transfer, heat transfer
risks across » risk across, costs across, firms across
transfers i » transfers ai, transfers im, transfers _
angel data » panel data, intel data
luis a » luis f, luis c

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 angel data transfer risks across ) OR ( luis a _ transfers i (acao OR cacao) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis angel data transfer risks across ) or ( luis a _ transfers i (acao OR cacao) ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis angel data transfer risks across ) or ( luis a _ transfers i (acao OR cacao) ))*.
