Perhaps you should try some spelling variations:
abierto ana » abierto en, abierto al
abierta 1 » abiertas 1, abierta y, abierta a
a 1860 » la 1860, a 1850, a 1820
d 1880 » de 1880, a 1880, v 1880
80 de » 20 de, 10 de, 40 de
mar a » mar y
mar d » mar de, mar y
1 30 » 1 20, 1 50, 1 3

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierto ana 80 de mar a 1860 ) OR ( Cabildo abierta 1 30 de mar d 1880 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto ana 80 de mar a 1860 ) OR ( Cabildo abierta 1 30 de mar d 1880 ))*.
