• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierto al 11 el max a 1820 ) OR ( Cabildo abierta ((al 10) OR (8 10)) de mar a 1880 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto al 11 el max a 1820 ) OR ( Cabildo abierta ((al 10) OR (8 10)) de mar a 1880 ))*.
