Perhaps you should try some spelling variations:
abierto y » abierta y, abierto en, aborto y
aborto 1 » aborto y, aborto _, aborto a
autor 1 » autor y, autor a, autor de
a 1300 » a 100, a 300, _ 1300
17 de » 1 de, 12 de
mar a » mar y
1 30 » 1 20, 1 50, 1 3
1 40 » 1 20, 1 50
y 17 » y 10, 1 17, y 13

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 aborto 1 30 de autor 1 40 ) OR ( Cabildo abierto y 17 de mar a 1300 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo aborto 1 30 de autor 1 40 ) OR ( Cabildo abierto y 17 de mar a 1300 ))*.
