• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierta de 1900 de mar a 1887 ) OR ( Cabildo abierto al 17 de fines a 1820 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 1900 de mar a 1887 ) OR ( Cabildo abierto al 17 de fines a 1820 ))*.
