Try widening your search to All Fields.

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 2015") or ((("ley 030 de 2015") OR ("ley 038 de 2015"))))) or ("ley 1563 de 2012"))) or ("ley 1523 de 2016"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1530 de 2015") OR ((("ley 030 de 2015") OR ("ley 038 de 2015"))))) OR ("ley 1563 de 2012"))) OR ("ley 1523 de 2016")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1530 de 2015\") or (((\"ley 030 de 2015\") OR (\"ley 038 de 2015\"))))) or (\"ley 1563 de 2012\"))) or (\"ley 1523 de 2016\"))".
• Removing quotes may allow a broader search: (((((( ley 1530 de 2015 ) or ((( ley 030 de 2015 ) OR ( ley 038 de 2015 ))))) or ( ley 1563 de 2012 ))) or ( ley 1523 de 2016 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1530 de 2015") or ((("ley 030 de 2015") OR ("ley 038 de 2015"))))) or ("ley 1563 de 2012"))) or ("ley 1523 de 2016"))*.
