Perhaps you should try some spelling variations:
3 transformers » 3 transformer, _ transformers, _ transformer
ion transport » road transport, main transport, bus transport
transport can » transport a, transport cost, transport data
guias key » guias de
can acao » can act, can also
4.3 can » 4.3 cnn, 4.3 clean, 4.3 case
2.3 can » 2.3 case
f ion » _ ion, 3 ion, 4 ion
key 3 » key _

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 f ion transport can acao ) OR ( guias key 3 transformers ((4.3 can) OR (2.3 can)) ))~.
• Adding a wildcard symbol may retrieve word variants: (( luis f ion transport can acao ) or ( guias key 3 transformers ((4.3 can) or (2.3 can)) ))*.
