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

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 da ley."))) or ((("codigo 1 ley.") or ("codigo en ley."))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("codigo 2da ley.") OR ("codigo da ley."))) OR ((("codigo 1 ley.") OR ("codigo en ley."))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"codigo 2da ley.\") OR (\"codigo da ley.\"))) or (((\"codigo 1 ley.\") or (\"codigo en ley.\"))))*".
• Removing quotes may allow a broader search: (((( codigo 2da ley. ) OR ( codigo da ley. ))) or ((( codigo 1 ley. ) or ( codigo en ley. ))))*.
