Perhaps you should try some spelling variations:
"codigo 2da ley." » "codigo da ley.", "codigo de ley.", "codigo yda ley.", "codigo deda ley.", "codigos yda ley."
"codigo l2 le." » "codigos la le.", "codigo de le.", "codigo y le.", "codigo l2 la."
"codigo en ley." » "codigo de ley.", "codigo penal ley.", "codigo en les."
"codigo 2 de." » "codigo y de.", "codigo de de.", "codigos y de.", "codigo _ de.", "codigo o de."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("codigo 2da ley.") OR ((((("codigo 2 de.") OR ("codigo l2 le."))) OR ("codigo en ley."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"codigo 2da ley.\") OR (((((\"codigo 2 de.\") OR (\"codigo l2 le.\"))) OR (\"codigo en ley.\"))))".
• Removing quotes may allow a broader search: (( codigo 2da ley. ) OR ((((( codigo 2 de. ) OR ( codigo l2 le. ))) OR ( codigo en ley. )))).
• Adding a wildcard symbol may retrieve word variants: (("codigo 2da ley.") OR ((((("codigo 2 de.") OR ("codigo l2 le."))) OR ("codigo en ley."))))*.
