Perhaps you should try some spelling variations:
"clave revuelta" » "la revuelta"
"slave revolt" » "llave revolt", "save revolt", "suave revolt", "slave revolte", "slave revol", "slave revolu"
"clave revolta" » "clave revoltea", "clave revola", "clave revolua", "clave rivolta", "clave travolta"
"clave revolua" » "clave revalua", "clave revolu", "clave revolucao"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("slave revolt") OR ((((("clave revolta") OR ("clave revuelta"))) OR ("clave revolua"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"slave revolt\") OR (((((\"clave revolta\") OR (\"clave revuelta\"))) OR (\"clave revolua\"))))*".
• Removing quotes may allow a broader search: (( slave revolt ) OR ((((( clave revolta ) OR ( clave revuelta ))) OR ( clave revolua ))))*.
