• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierta n 12 a basic de 30 ) OR ( Cabildo abierta 5 30 de mar de 1793 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta n 12 a basic de 30 ) OR ( Cabildo abierta 5 30 de mar de 1793 ))*.
