Perhaps you should try some spelling variations:
based transfers » basin transfers, cash transfers, land transfers
transfers 6 » transfers _, transfers 3, transfers 2
2 africa's » 2 african
_ africa's » _ african
aguas de » aguas del, aguas do, vagues de
de based » dge based, de base, de bases
costs a » costs _, costs 4
6 ao » 6 a, 6 co, 6 do

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: (( agudo ((2 africa's) OR (_ africa's)) transport costs a ) OR ( aguas de based transfers 6 ao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( agudo ((2 africa's) OR (_ africa's)) transport costs a ) or ( aguas de based transfers 6 ao ))~".
• Adding a wildcard symbol may retrieve word variants: (( agudo ((2 africa's) OR (_ africa's)) transport costs a ) or ( aguas de based transfers 6 ao ))*.
