• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 153 de 2016\") OR (\"ley 153 de 2015\"))) or (\"((ley 1563) or (ley 1581)) de 2016\"))) or (\"ley 1030 de 2012\"))".
• Removing quotes may allow a broader search: (((((( ley 153 de 2016 ) OR ( ley 153 de 2015 ))) or ( ((ley 1563) or (ley 1581)) de 2016 ))) or ( ley 1030 de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 153 de 2016") OR ("ley 153 de 2015"))) or ("((ley 1563) or (ley 1581)) de 2016"))) or ("ley 1030 de 2012"))*.
