Perhaps you should try some spelling variations:
ley 1340 » ley 1341, ley 1480, ley 1448
ley 1934 » ley 1341, ley 1437, ley 1438
1934 del » 1934 de, 14 del, 1164 del
del 2018 » de 2018, del 2015, del 2006
ley 1944 » ley 1943, ley 1341, ley 1448
1944 del » 14 del, 1164 del, 1943 de
del 2012 » del 2015, del 2016, del 2006
ley 1090 » ley 1098, ley 1480
de 2012 » de 2015
de 2016 » de 2015

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((ley 1340) OR (ley 100)) ((de 2012) OR (de 2016)) ) OR ((( ley 1934 del 2018 ) OR ( ley 1944 del 2012 ))))) OR ( ley 1090 ((de 2012) OR (de 2016)) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((ley 1340) OR (ley 100)) ((de 2012) or (de 2016)) ) or ((( ley 1934 del 2018 ) or ( ley 1944 del 2012 ))))) or ( ley 1090 ((de 2012) or (de 2016)) ))~".
• Adding a wildcard symbol may retrieve word variants: (((( ((ley 1340) OR (ley 100)) ((de 2012) or (de 2016)) ) or ((( ley 1934 del 2018 ) or ( ley 1944 del 2012 ))))) or ( ley 1090 ((de 2012) or (de 2016)) ))*.
