• The words AND, OR and NOT may confuse the search; try adding quotes: "(( Cabildo aborto 1 10 de autores 1 20 ) OR ( Cabildo abierta v 14 de martin pena 80 ))~".
• Adding a wildcard symbol may retrieve word variants: (( Cabildo aborto 1 10 de autores 1 20 ) OR ( Cabildo abierta v 14 de martin pena 80 ))*.
