• If you are trying to use Boolean operators, they must be ALL CAPS: (((("insurrection of 18 august 1794") OR ("insurrection of 18 august 1798"))) OR ("insurrection of 1 august 1794")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"insurrection of 18 august 1794\") OR (\"insurrection of 18 august 1798\"))) or (\"insurrection of 1 august 1794\"))".
• Removing quotes may allow a broader search: (((( insurrection of 18 august 1794 ) OR ( insurrection of 18 august 1798 ))) or ( insurrection of 1 august 1794 )).
• Adding a wildcard symbol may retrieve word variants: (((("insurrection of 18 august 1794") OR ("insurrection of 18 august 1798"))) or ("insurrection of 1 august 1794"))*.
