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