Perhaps you should try some spelling variations:
"codigo delta de." » "codigo del de.", "codigo de de.", "codigo da de.", "codigo vuelta de.", "codigo falta de."
"codigo 2da ley." » "codigo da ley.", "codigo de ley.", "codigo yda ley.", "codigo deda ley.", "codigo enda ley."
"codigo 2la ley." » "codigos la ley.", "codigo da ley.", "codigo yla ley.", "codigo dela ley.", "codigo enla ley.", "codigo la ley.", "codigo sola 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 2da ley.") OR ((((("codigo 2la ley.") OR ("codigo delta de."))) OR ("codigo 2 ley."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"codigo 2da ley.\") OR (((((\"codigo 2la ley.\") OR (\"codigo delta de.\"))) OR (\"codigo 2 ley.\"))))".
• Removing quotes may allow a broader search: (( codigo 2da ley. ) OR ((((( codigo 2la ley. ) OR ( codigo delta de. ))) OR ( codigo 2 ley. )))).
• Adding a wildcard symbol may retrieve word variants: (("codigo 2da ley.") OR ((((("codigo 2la ley.") OR ("codigo delta de."))) OR ("codigo 2 ley."))))*.
