Perhaps you should try some spelling variations:
del mario » del marco, de mario, del diario
abierta a » abierta 5, abierto y
mario de » marco de, maria de, maria del
de 1930 » de 1960
11 del » 11 de
de 20 » de 2
1 de » y de, _ de, o de
a 11 » 9 11, _ 11, a 1

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 de caso de 20 ) OR ( Cabildo abierta a 11 del mario de 1930 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo aborto _ 1 de caso de 20 ) OR ( Cabildo abierta a 11 del mario de 1930 ))*.
