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: (("insurrection of 18 august 1794") OR ((("insurrection of 1 august 1794") OR ("insurrection of 31 august 1794")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"insurrection of 18 august 1794\") or (((\"insurrection of 1 august 1794\") OR (\"insurrection of 31 august 1794\"))))".
• Removing quotes may allow a broader search: (( insurrection of 18 august 1794 ) or ((( insurrection of 1 august 1794 ) OR ( insurrection of 31 august 1794 )))).
• Adding a wildcard symbol may retrieve word variants: (("insurrection of 18 august 1794") or ((("insurrection of 1 august 1794") OR ("insurrection of 31 august 1794"))))*.
