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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("ley 1537 de 2015") or ((("ley 2153 de 2012") OR ("ley 2155 de 2012"))))) or ("((((ley 1010) or (ley 1014))) or (((ley 1090) or (ley 1098)))) de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1537 de 2015") OR ((("ley 2153 de 2012") OR ("ley 2155 de 2012"))))) OR ("((((ley 1010) or (ley 1014))) or (((ley 1090) or (ley 1098)))) de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1537 de 2015\") or (((\"ley 2153 de 2012\") OR (\"ley 2155 de 2012\"))))) or (\"((((ley 1010) or (ley 1014))) or (((ley 1090) or (ley 1098)))) de 2012\"))".
• Removing quotes may allow a broader search: (((( ley 1537 de 2015 ) or ((( ley 2153 de 2012 ) OR ( ley 2155 de 2012 ))))) or ( ((((ley 1010) or (ley 1014))) or (((ley 1090) or (ley 1098)))) de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((("ley 1537 de 2015") or ((("ley 2153 de 2012") OR ("ley 2155 de 2012"))))) or ("((((ley 1010) or (ley 1014))) or (((ley 1090) or (ley 1098)))) de 2012"))*.
