• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"secret ballot\") OR (((\"secreto ballot\") OR (\"secreto bellot\"))))) OR (\"secret ballo\"))".
• Removing quotes may allow a broader search: (((( secret ballot ) OR ((( secreto ballot ) OR ( secreto bellot ))))) OR ( secret ballo )).
• Adding a wildcard symbol may retrieve word variants: (((("secret ballot") OR ((("secreto ballot") OR ("secreto bellot"))))) OR ("secret ballo"))*.
