Perhaps you should try some spelling variations:
"ley 1083 de 2015-colombia" » "ley 1383 de 2015-colombia", "ley 1283 de 2015-colombia", "ley 100 de 2015-colombia", "ley 103 de 2015-colombia", "ley 1043 de 2015-colombia"
"ley 1477 de 2011-colombia" » "ley 1474 de 2011-colombia", "ley 1475 de 2011-colombia", "ley 1407 de 2011-colombia"
"ley 1477 de 2012-colombia" » "ley 1474 de 2012-colombia", "ley 1475 de 2012-colombia", "ley 1407 de 2012-colombia"
"ley 1437 de 2016-colombia" » "ley 1480 de 2016-colombia", "ley 1448 de 2016-colombia"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("ley 1083 de 2015-colombia") OR ((("ley 1477 de 2011-colombia") OR ("ley 1477 de 2012-colombia"))))) OR ("ley 1437 de 2016-colombia"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 1083 de 2015-colombia\") or (((\"ley 1477 de 2011-colombia\") OR (\"ley 1477 de 2012-colombia\"))))) or (\"ley 1437 de 2016-colombia\"))~".
• Removing quotes may allow a broader search: (((( ley 1083 de 2015-colombia ) or ((( ley 1477 de 2011-colombia ) OR ( ley 1477 de 2012-colombia ))))) or ( ley 1437 de 2016-colombia ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ley 1083 de 2015-colombia") or ((("ley 1477 de 2011-colombia") OR ("ley 1477 de 2012-colombia"))))) or ("ley 1437 de 2016-colombia"))*.
