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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 15370 de 2012") OR ("ley 153770 de 2012"))) or ((("ley 153 de 2016") or ("ley 1563 de 2012"))))) or ("((((ley 1010) or (ley 1014))) or (ley 1090)) de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 15370 de 2012") OR ("ley 153770 de 2012"))) OR ((("ley 153 de 2016") OR ("ley 1563 de 2012"))))) OR ("((((ley 1010) or (ley 1014))) or (ley 1090)) de 2012"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 15370 de 2012\") OR (\"ley 153770 de 2012\"))) or (((\"ley 153 de 2016\") or (\"ley 1563 de 2012\"))))) or (\"((((ley 1010) or (ley 1014))) or (ley 1090)) de 2012\"))*".
• Removing quotes may allow a broader search: (((((( ley 15370 de 2012 ) OR ( ley 153770 de 2012 ))) or ((( ley 153 de 2016 ) or ( ley 1563 de 2012 ))))) or ( ((((ley 1010) or (ley 1014))) or (ley 1090)) de 2012 ))*.
