Perhaps you should try some spelling variations:
has transformer » has transformed, a transformer, ray transformer
transformer 1 » transformer _, transformed _
transfers ai » transfers bei, transfers dau, transfers ein
transfers i » transfers im, transfers _, transfers 3
a federal » _ federal
luis a » luis f, 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 _ has transformer 1 a ) OR ( luis a federal ((transfers ai) OR (transfers i)) cmcacao ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis _ has transformer 1 a ) or ( luis a federal ((transfers ai) OR (transfers i)) cmcacao ))~".
• Adding a wildcard symbol may retrieve word variants: (( luis _ has transformer 1 a ) or ( luis a federal ((transfers ai) OR (transfers i)) cmcacao ))*.
