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

• Performing a fuzzy search may retrieve terms with similar spellings: (((( ((((ley 143) or (ley 1413))) or (ley 1943)) ((de 2010) OR (de 2012))-colombia ) or ( ley ((1121 de) or (1421 de)) 2010-colombia ))) or ( ley 1437 de 2015-colombia ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((( ((((ley 143) OR (ley 1413))) OR (ley 1943)) ((de 2010) OR (de 2012))-colombia ) OR ( ley ((1121 de) OR (1421 de)) 2010-colombia ))) OR ( ley 1437 de 2015-colombia )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( ((((ley 143) or (ley 1413))) or (ley 1943)) ((de 2010) OR (de 2012))-colombia ) or ( ley ((1121 de) or (1421 de)) 2010-colombia ))) or ( ley 1437 de 2015-colombia ))".
• Adding a wildcard symbol may retrieve word variants: (((( ((((ley 143) or (ley 1413))) or (ley 1943)) ((de 2010) OR (de 2012))-colombia ) or ( ley ((1121 de) or (1421 de)) 2010-colombia ))) or ( ley 1437 de 2015-colombia ))*.
