Perhaps you should try some spelling variations:
"ley 1477 de 2010-colombia" » "ley 1437 de 2010-colombia", "ley 1474 de 2010-colombia", "ley 1475 de 2010-colombia", "ley 1477 de 2012-colombia", "ley 1477 de 2013-colombia", "ley 1477 de 2014-colombia"
"ley 1477 de 2017-colombia" » "ley 1437 de 2017-colombia", "ley 1474 de 2017-colombia", "ley 1475 de 2017-colombia", "ley 1477 de 2012-colombia"
"ley 1477 de 2011-colombia" » "ley 1437 de 2011-colombia", "ley 1474 de 2011-colombia", "ley 1475 de 2011-colombia", "ley 1477 de 2012-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 103 de 2015-colombia") OR ((((("ley 1477 de 2010-colombia") OR ("ley 1477 de 2017-colombia"))) OR ("ley 1477 de 2011-colombia"))))) OR ("ley 1943 de 2016-colombia"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ley 103 de 2015-colombia\") or (((((\"ley 1477 de 2010-colombia\") OR (\"ley 1477 de 2017-colombia\"))) or (\"ley 1477 de 2011-colombia\"))))) or (\"ley 1943 de 2016-colombia\"))~".
• Removing quotes may allow a broader search: (((( ley 103 de 2015-colombia ) or ((((( ley 1477 de 2010-colombia ) OR ( ley 1477 de 2017-colombia ))) or ( ley 1477 de 2011-colombia ))))) or ( ley 1943 de 2016-colombia ))~.
• Adding a wildcard symbol may retrieve word variants: (((("ley 103 de 2015-colombia") or ((((("ley 1477 de 2010-colombia") OR ("ley 1477 de 2017-colombia"))) or ("ley 1477 de 2011-colombia"))))) or ("ley 1943 de 2016-colombia"))*.
