• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abiertas 1 10 un mundo 2 15 ) OR ( Cabildo abierta a 12 de mar a 1820 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abiertas 1 10 un mundo 2 15 ) OR ( Cabildo abierta a 12 de mar a 1820 ))*.
