• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierto al 1 el mas a 1820 ) OR ( Cabildo abiertas 1 30 de normas a 1860 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierto al 1 el mas a 1820 ) OR ( Cabildo abiertas 1 30 de normas a 1860 ))*.
