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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1090 de 2016") or ((("ley 1014 de 2015") OR ("ley 101 de 2015"))))) or ("ley 1011 de 2016"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1090 de 2016") OR ((("ley 1014 de 2015") OR ("ley 101 de 2015"))))) OR ("ley 1011 de 2016")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1090 de 2016\") or (((\"ley 1014 de 2015\") OR (\"ley 101 de 2015\"))))) or (\"ley 1011 de 2016\"))".
• Removing quotes may allow a broader search: (((( ley 1090 de 2016 ) or ((( ley 1014 de 2015 ) OR ( ley 101 de 2015 ))))) or ( ley 1011 de 2016 )).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1090 de 2016") or ((("ley 1014 de 2015") OR ("ley 101 de 2015"))))) or ("ley 1011 de 2016"))*.
