• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"1998 brazilian scenario election\") OR (\"12th brazilian scenario election\"))) or (\"1998 brazilian central reflection\"))".
• Removing quotes may allow a broader search: (((( 1998 brazilian scenario election ) OR ( 12th brazilian scenario election ))) or ( 1998 brazilian central reflection )).
• Adding a wildcard symbol may retrieve word variants: (((("1998 brazilian scenario election") OR ("12th brazilian scenario election"))) or ("1998 brazilian central reflection"))*.
