Perhaps you should try some spelling variations:
abierta a » abierta y, abiertas 1, abierta en
guerra o » guerra y, guerra a, guerra _
a 1087 » a 1887, a 1987
de 20 » del 20, de 2, de 0
20 la » 2 la, 10 la, 22 la
17 de » 1 de, 12 de
mar a » mar y
a 17 » ac 17, al 17, a 7
o 8 » op 8

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 abierta de 20 la guerra o 8 ) OR ( Cabildo abierta a 17 de mar a 1087 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 20 la guerra o 8 ) OR ( Cabildo abierta a 17 de mar a 1087 ))*.
