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 2012") or ((("ley 1934 de 2016") OR ("ley 1834 de 2016"))))) or ("ley 1310 de 2015"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1340 de 2012") OR ((("ley 1934 de 2016") OR ("ley 1834 de 2016"))))) OR ("ley 1310 de 2015")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1340 de 2012\") or (((\"ley 1934 de 2016\") OR (\"ley 1834 de 2016\"))))) or (\"ley 1310 de 2015\"))".
• Removing quotes may allow a broader search: (((( ley 1340 de 2012 ) or ((( ley 1934 de 2016 ) OR ( ley 1834 de 2016 ))))) or ( ley 1310 de 2015 )).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1340 de 2012") or ((("ley 1934 de 2016") OR ("ley 1834 de 2016"))))) or ("ley 1310 de 2015"))*.
