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 1943 de 2012-colombia") OR ("ley 1443 de 2012-colombia"))) OR ("ley 143787 de 2010-colombia"))) OR ("ley 143 de 2016-colombia"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1943 de 2012-colombia\") OR (\"ley 1443 de 2012-colombia\"))) or (\"ley 143787 de 2010-colombia\"))) or (\"ley 143 de 2016-colombia\"))~".
• Removing quotes may allow a broader search: (((((( ley 1943 de 2012-colombia ) OR ( ley 1443 de 2012-colombia ))) or ( ley 143787 de 2010-colombia ))) or ( ley 143 de 2016-colombia ))~.
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1943 de 2012-colombia") OR ("ley 1443 de 2012-colombia"))) or ("ley 143787 de 2010-colombia"))) or ("ley 143 de 2016-colombia"))*.
