Perhaps you should try some spelling variations:
abierto ana » abierto en, abierto al
a 1500 » al 1500, a 100, a 500
e 1960 » de 1960, e 1940, y 1960
de 30 » del 30, de 0, de 20
mar a » mar y
ana 6 » ana m, ana c, ana r
mar e » mar de, mar en, mar el
6 de » 16 de, y de, 1 de

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 30 de mar a 1500 ) OR ( Cabildo abierto ana 6 de mar e 1960 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 30 de mar a 1500 ) OR ( Cabildo abierto ana 6 de mar e 1960 ))*.
