Perhaps you should try some spelling variations:
slave » clave, save, llave
revol » revolt, resol, revel
revolu » revoltu, resolu, revelu, revolt
revolta » revoltta, resolta, revelta, revuelta
revoltta » revolttta, resoltta, reveltta, revolt
reveltae » revueltas, revela, revelan
travolta » travela, traviata

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: (( slave (revol OR revolu) ) OR ( slave ((reveltae OR revolta) OR (revoltta OR travolta ))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( slave (revol OR revolu) ) OR ( slave ((reveltae OR revolta) OR (revoltta OR travolta ))))~".
• Adding a wildcard symbol may retrieve word variants: (( slave (revol OR revolu) ) OR ( slave ((reveltae OR revolta) OR (revoltta OR travolta ))))*.
