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

• Performing a fuzzy search may retrieve terms with similar spellings: (("ley 1530 de 2012") or ((((((("Ley 1530 de 2015") OR ("Ley 153 de 2015"))) or ("ley 1500 de 2015"))) or ("ley 1330 de 2015"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("ley 1530 de 2012") OR ((((((("Ley 1530 de 2015") OR ("Ley 153 de 2015"))) OR ("ley 1500 de 2015"))) OR ("ley 1330 de 2015")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ley 1530 de 2012\") or (((((((\"Ley 1530 de 2015\") OR (\"Ley 153 de 2015\"))) or (\"ley 1500 de 2015\"))) or (\"ley 1330 de 2015\"))))".
• Removing quotes may allow a broader search: (( ley 1530 de 2012 ) or ((((((( Ley 1530 de 2015 ) OR ( Ley 153 de 2015 ))) or ( ley 1500 de 2015 ))) or ( ley 1330 de 2015 )))).
• Adding a wildcard symbol may retrieve word variants: (("ley 1530 de 2012") or ((((((("Ley 1530 de 2015") OR ("Ley 153 de 2015"))) or ("ley 1500 de 2015"))) or ("ley 1330 de 2015"))))*.
