data transfer » cash transfer, heat transfer
des transfers » net transfers, cash transfers, data transfers
luis dlf » luis f, luis de
dlf data » imf data, rdf data
i maria » vi maria, 3 maria, avi maria
luis c » luis f
arms » farms, aims, arts

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