federal transfers » central transfers, fiscal transfers
has transformer » has transformed, a transformer, ray transformer
transformer 1 » transformer _, transformed _
transfers ai » transfers i, transfers bei, transfers dau
a federal » _ federal
luis a » luis f, luis c
1 ao » 1 a, 1 do, 1 co

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 _ has transformer 1 ao ) OR ( luis a federal transfers ai cmcacao ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis _ has transformer 1 ao ) or ( luis a federal transfers ai cmcacao ))*.
