• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ley 1530 de 2012\") or (((((\"ley 1330 de 2012\") OR (\"ley 1340 de 2012\"))) or (\"((ley 1333) or (ley 1438)) de 2012\"))))".
• Removing quotes may allow a broader search: (( ley 1530 de 2012 ) or ((((( ley 1330 de 2012 ) OR ( ley 1340 de 2012 ))) or ( ((ley 1333) or (ley 1438)) de 2012 )))).
• Adding a wildcard symbol may retrieve word variants: (("ley 1530 de 2012") or ((((("ley 1330 de 2012") OR ("ley 1340 de 2012"))) or ("((ley 1333) or (ley 1438)) de 2012"))))*.
