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 2012") OR ("ley 137 de 2012"))) or ("ley 153 de 2012"))) or ((("ley 1437 de 2012") or ("ley 1819 de 2012"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1537 de 2012") OR ("ley 137 de 2012"))) OR ("ley 153 de 2012"))) OR ((("ley 1437 de 2012") OR ("ley 1819 de 2012")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1537 de 2012\") OR (\"ley 137 de 2012\"))) or (\"ley 153 de 2012\"))) or (((\"ley 1437 de 2012\") or (\"ley 1819 de 2012\"))))".
• Removing quotes may allow a broader search: (((((( ley 1537 de 2012 ) OR ( ley 137 de 2012 ))) or ( ley 153 de 2012 ))) or ((( ley 1437 de 2012 ) or ( ley 1819 de 2012 )))).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1537 de 2012") OR ("ley 137 de 2012"))) or ("ley 153 de 2012"))) or ((("ley 1437 de 2012") or ("ley 1819 de 2012"))))*.
