Perhaps you should try some spelling variations:
dos tareas » dos areas, dos caras, las tareas
tareas del » tareas de, areas de, tarea de
abierta 3 » abierta y, abierta a, abierta 5
de 1850 » de 1880, de 1810, de 1820
la dos » la des, la diosa, lira dos
mar de » mar del
3 12 » 31 12, 03 12, 13 12

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 y la dos tareas del 80 ) OR ( Cabildo abierta 3 12 de mar de 1850 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo aborto y la dos tareas del 80 ) OR ( Cabildo abierta 3 12 de mar de 1850 ))*.
