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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 1380 de 2015") OR ("ley 1383 de 2015"))) or ((("ley 1819 de 2012") or ("ley 1437 de 2012"))))) or ("ley 1310 de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1380 de 2015") OR ("ley 1383 de 2015"))) OR ((("ley 1819 de 2012") OR ("ley 1437 de 2012"))))) OR ("ley 1310 de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1380 de 2015\") OR (\"ley 1383 de 2015\"))) or (((\"ley 1819 de 2012\") or (\"ley 1437 de 2012\"))))) or (\"ley 1310 de 2012\"))".
• Removing quotes may allow a broader search: (((((( ley 1380 de 2015 ) OR ( ley 1383 de 2015 ))) or ((( ley 1819 de 2012 ) or ( ley 1437 de 2012 ))))) or ( ley 1310 de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1380 de 2015") OR ("ley 1383 de 2015"))) or ((("ley 1819 de 2012") or ("ley 1437 de 2012"))))) or ("ley 1310 de 2012"))*.
