• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ley 1380 de 2012 ) OR ((( ley 1437 del 2006 ) OR ( ley 1944 del 2015 ))))) OR ( ((ley 1340) OR (ley 1480)) de 2012 ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ley 1380 de 2012 ) or ((( ley 1437 del 2006 ) or ( ley 1944 del 2015 ))))) or ( ((ley 1340) OR (ley 1480)) de 2012 ))~".
• Adding a wildcard symbol may retrieve word variants: (((( ley 1380 de 2012 ) or ((( ley 1437 del 2006 ) or ( ley 1944 del 2015 ))))) or ( ((ley 1340) OR (ley 1480)) de 2012 ))*.
