Perhaps you should try some spelling variations:
transforming signal » transforming social, transform signal, transforming legal
lage transfer » large transfer, wage transfer, large transfers
guias die » guias de, guia de, bias die
signal 3 » signals 3, signal _, signal 4
4 roles » _ roles, 7 roles, 8 roles
4 role » 3 role

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: (( arts ((4 roles) OR (4 role)) transforming signal 3 ) OR ( guias die lage transfer _ case ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( arts ((4 roles) OR (4 role)) transforming signal 3 ) or ( guias die lage transfer _ case ))~".
• Adding a wildcard symbol may retrieve word variants: (( arts ((4 roles) OR (4 role)) transforming signal 3 ) or ( guias die lage transfer _ case ))*.
