Perhaps you should try some spelling variations:
"ley 1503 de 2015" » "ley 1563 de 2015", "ley 1508 de 2015", "ley 1523 de 2015", "ley 11503 de 2015", "ley 15083 de 2015", "ley 15303 de 2015", "ley 1500 de 2015", "ley 103 de 2015"
"ley 1330 de 2012" » "ley 1340 de 2012", "ley 1335 de 2012", "ley 1310 de 2012", "ley 1330 de 2016"
"ley 1850 de 2012" » "ley 1150 de 2012", "ley 115 de 2012", "ley 1480 de 2012", "ley 1850 de 2016", "ley 1860 de 2012"
"ley 1333 de 2012" » "ley 1341 de 2012", "ley 1437 de 2012", "ley 1438 de 2012", "ley 1333 de 2016"
"ley 100 de 2012" » "ley 100 de 2016"
"ley 150 de 2015" » "ley 1150 de 2015", "ley 1508 de 2015", "ley 1530 de 2015", "ley 1500 de 2015"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((((("ley 1330 de 2012") or ((((("ley 150 de 2015") OR ("ley 1503 de 2015"))) or ("ley 1850 de 2012"))))) or ("ley 1333 de 2012"))) or ("ley 100 de 2012"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((((("ley 1330 de 2012") OR ((((("ley 150 de 2015") OR ("ley 1503 de 2015"))) OR ("ley 1850 de 2012"))))) OR ("ley 1333 de 2012"))) OR ("ley 100 de 2012")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"ley 1330 de 2012\") or (((((\"ley 150 de 2015\") OR (\"ley 1503 de 2015\"))) or (\"ley 1850 de 2012\"))))) or (\"ley 1333 de 2012\"))) or (\"ley 100 de 2012\"))".
• Removing quotes may allow a broader search: (((((( ley 1330 de 2012 ) or ((((( ley 150 de 2015 ) OR ( ley 1503 de 2015 ))) or ( ley 1850 de 2012 ))))) or ( ley 1333 de 2012 ))) or ( ley 100 de 2012 )).
• Adding a wildcard symbol may retrieve word variants: (((((("ley 1330 de 2012") or ((((("ley 150 de 2015") OR ("ley 1503 de 2015"))) or ("ley 1850 de 2012"))))) or ("ley 1333 de 2012"))) or ("ley 100 de 2012"))*.
