Perhaps you should try some spelling variations:
abierta v » abierta y, abierta a, abierta 5
basic de » basica de, basico de, basicos de
y 1957 » y 1950, y 1967, a 1957
11 de » 12 de, 17 de, 16 de
mar y » mar a, mas y
de 0 » de 20, de 30, de 40
v 11 » v 1, v 14, 9 11
1 4 » 1 40, 1 24, 1 14

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 abiertas 1 4 _ basic de 0 ) OR ( Cabildo abierta v 11 de mar y 1957 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abiertas 1 4 _ basic de 0 ) OR ( Cabildo abierta v 11 de mar y 1957 ))*.
