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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1523 de 2015") or ((("ley 123 de 2015") OR ("ley 1273 de 2015"))))) or ("((((ley 1500) or (ley 1508))) or (ley 100)) de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1523 de 2015") OR ((("ley 123 de 2015") OR ("ley 1273 de 2015"))))) OR ("((((ley 1500) or (ley 1508))) or (ley 100)) de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1523 de 2015\") or (((\"ley 123 de 2015\") OR (\"ley 1273 de 2015\"))))) or (\"((((ley 1500) or (ley 1508))) or (ley 100)) de 2012\"))".
• Removing quotes may allow a broader search: (((( ley 1523 de 2015 ) or ((( ley 123 de 2015 ) OR ( ley 1273 de 2015 ))))) or ( ((((ley 1500) or (ley 1508))) or (ley 100)) de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1523 de 2015") or ((("ley 123 de 2015") OR ("ley 1273 de 2015"))))) or ("((((ley 1500) or (ley 1508))) or (ley 100)) de 2012"))*.
