• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierto 1 12 de mar o 1886 ) OR ( Cabildo abierta de 16 de pedro a 1883 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto 1 12 de mar o 1886 ) OR ( Cabildo abierta de 16 de pedro a 1883 ))*.
