• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo abierta de 17 de teoria y _ ) OR ( Cabildo abiertas 1 80 de marx a 1907 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo abierta de 17 de teoria y _ ) OR ( Cabildo abiertas 1 80 de marx a 1907 ))*.
