Perhaps you should try some spelling variations:
abierto ana » abierto en, abierto al
y mariano » y maria
mariano f » mariano d, mariano h, mariano n
de aulas » de aula, de alas, de abuelas
f 1810 » fe 1810
20 de » 2 de, 30 de, 24 de
1 17 » 1 1, 1 15, 1 10
17 y » 1 y, 10 y, 11 y

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 20 de aulas _ 1930 ) OR ( Cabildo abiertas 1 17 y mariano f 1810 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto ana 20 de aulas _ 1930 ) OR ( Cabildo abiertas 1 17 y mariano f 1810 ))*.
