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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1340 de 2016") or ("ley 1448 de 2016"))) or ((((("ley 2153 de 2015") OR ("ley 2155 de 2015"))) or ("ley 1030 de 2015"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1340 de 2016") OR ("ley 1448 de 2016"))) OR ((((("ley 2153 de 2015") OR ("ley 2155 de 2015"))) OR ("ley 1030 de 2015")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1340 de 2016\") or (\"ley 1448 de 2016\"))) or (((((\"ley 2153 de 2015\") OR (\"ley 2155 de 2015\"))) or (\"ley 1030 de 2015\"))))".
• Removing quotes may allow a broader search: (((( ley 1340 de 2016 ) or ( ley 1448 de 2016 ))) or ((((( ley 2153 de 2015 ) OR ( ley 2155 de 2015 ))) or ( ley 1030 de 2015 )))).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1340 de 2016") or ("ley 1448 de 2016"))) or ((((("ley 2153 de 2015") OR ("ley 2155 de 2015"))) or ("ley 1030 de 2015"))))*.
