Perhaps you should try some spelling variations:
based transfers » basin transfers, cash transfers, land transfers
transport cost » transport costs
transfers a » transfers ai, transfers _, transfer a
aguas dol » aguas del, aguas do, aguas de
aguas dot » aguas do, aguas de, aguas del
dot based » iot based, dlt based, data based

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: (( aguas dol bus transport cost _ ) OR ( aguas dot based transfers a la ))~.
• Adding a wildcard symbol may retrieve word variants: (( aguas dol bus transport cost _ ) or ( aguas dot based transfers a la ))*.
