Perhaps you should try some spelling variations:
"ley 1330 de 2012" » "ley 1340 de 2012", "ley 1333 de 2012", "ley 1310 de 2012"
"ley 1335 de 2012" » "ley 1333 de 2012", "ley 1355 de 2012", "ley 115 de 2012", "ley 135 de 2012"
"ley 1930 de 2015" » "ley 1934 de 2015", "ley 130 de 2015", "ley 1530 de 2015", "ley 190 de 2015"
"ley 1030 de 2015" » "ley 100 de 2015", "ley 1090 de 2015", "ley 1010 de 2015"
"ley 390 de 2012" » "ley 30 de 2012", "ley 397 de 2012", "ley 39 de 2012"
"ley 390 de 2016" » "ley 30 de 2016", "ley 397 de 2016", "ley 39 de 2016"

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 1330 de 2012") OR ("ley 1335 de 2012"))) OR ((("ley 390 de 2012") OR ("ley 390 de 2016"))))) OR ((("ley 1930 de 2015") OR ("ley 1030 de 2015"))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1330 de 2012\") or (\"ley 1335 de 2012\"))) or (((\"ley 390 de 2012\") OR (\"ley 390 de 2016\"))))) or (((\"ley 1930 de 2015\") or (\"ley 1030 de 2015\"))))~".
• Removing quotes may allow a broader search: (((((( ley 1330 de 2012 ) or ( ley 1335 de 2012 ))) or ((( ley 390 de 2012 ) OR ( ley 390 de 2016 ))))) or ((( ley 1930 de 2015 ) or ( ley 1030 de 2015 ))))~.
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1330 de 2012") or ("ley 1335 de 2012"))) or ((("ley 390 de 2012") OR ("ley 390 de 2016"))))) or ((("ley 1930 de 2015") or ("ley 1030 de 2015"))))*.
