• Performing a fuzzy search may retrieve terms with similar spellings: (((("slave revolt") OR ("slave revol"))) OR ((("slave revolte") OR ("slave revolver"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"slave revolt\") OR (\"slave revol\"))) OR (((\"slave revolte\") OR (\"slave revolver\"))))".
• Removing quotes may allow a broader search: (((( slave revolt ) OR ( slave revol ))) OR ((( slave revolte ) OR ( slave revolver )))).
• Adding a wildcard symbol may retrieve word variants: (((("slave revolt") OR ("slave revol"))) OR ((("slave revolte") OR ("slave revolver"))))*.
