Perhaps you should try some spelling variations:
"clave revuelta" » "la revuelta"
"slave revolt" » "save revolt", "suave revolt", "lave revolt", "slave revolta", "slave revolte", "slave revolu", "slave revolut", "slave revelt", "slave evolt"
"llave revolt" » "llave revolta", "llave revolte", "llave revolu", "llave revolut", "llave revelt", "llave evolt"
"llave revol" » "llave revolu", "llave revel", "llave evol"

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 revuelta"))) OR ((("llave revolt") OR ("llave revol"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"slave revolt\") OR (\"clave revuelta\"))) OR (((\"llave revolt\") OR (\"llave revol\"))))*".
• Removing quotes may allow a broader search: (((( slave revolt ) OR ( clave revuelta ))) OR ((( llave revolt ) OR ( llave revol ))))*.
