transport data » transport demand
net transfer » net transfers, heat transfer, money transfer
transfer 3 » transfer _, transfer 4, transfer a
data cacao » data catalog
luis e » luis c
luis a » 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 e) OR (luis f)) net transfer 3 case ) OR ( luis a heat transport data cacao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((luis e) OR (luis f)) net transfer 3 case ) or ( luis a heat transport data cacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((luis e) OR (luis f)) net transfer 3 case ) or ( luis a heat transport data cacao ))*.
