Perhaps you should try some spelling variations:
tarea del » tareas del, tarea de, area de
abierta a » abierta y, abiertas 1, abierta en
del 90 » del 80
18 de » 1 de, 12 de, 17 de
mar a » mar y
de 8 » de i, de c, de _
8 la » y la, a la, 1 la
a 18 » al 18, a 10, 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 abierta de 8 la tarea del 90 ) OR ( Cabildo abierta a 18 de mar a 1887 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 8 la tarea del 90 ) OR ( Cabildo abierta a 18 de mar a 1887 ))*.
