Perhaps you should try some spelling variations:
"codigo dy ley." » "codigo de ley.", "codigo y ley.", "codigo da ley."
"codigo a ley." » "codigo da ley.", "codigo y ley.", "codigos la ley.", "codigo la ley.", "codigo a les."
"codigo 3 ley." » "codigo y ley.", "codigo de ley.", "codigo en ley.", "codigo 1 ley.", "codigo e ley."
"codigo 2 ley." » "codigo y ley.", "codigo de ley.", "codigo en ley.", "codigo 1 ley.", "codigo 2 le."

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("codigo dy ley.") OR ((((("codigo a ley.") OR ("codigo 3 ley."))) OR ("codigo 2 ley."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"codigo dy ley.\") OR (((((\"codigo a ley.\") OR (\"codigo 3 ley.\"))) OR (\"codigo 2 ley.\"))))".
• Removing quotes may allow a broader search: (( codigo dy ley. ) OR ((((( codigo a ley. ) OR ( codigo 3 ley. ))) OR ( codigo 2 ley. )))).
• Adding a wildcard symbol may retrieve word variants: (("codigo dy ley.") OR ((((("codigo a ley.") OR ("codigo 3 ley."))) OR ("codigo 2 ley."))))*.
