Perhaps you should try some spelling variations:
"continuo ni ley." » "continuo de ley.", "continuo en ley.", "continuo y ley.", "continuo ni leyes."
"codigo 2 ley." » "codigo de ley.", "codigo en ley.", "codigos y ley.", "codigo 1 ley.", "codigo 2 le.", "codigo 3 ley."
"codigo y ley." » "codigos y ley.", "codigo de ley.", "codigo en ley."
"contigo ni ley." » "contigo ni leyes.", "contagio ni ley."

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("contigo ni ley.") OR ("continuo ni ley."))) OR ((("codigo 2 ley.") OR ("codigo y ley."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"contigo ni ley.\") or (\"continuo ni ley.\"))) or (((\"codigo 2 ley.\") OR (\"codigo y ley.\"))))~".
• Removing quotes may allow a broader search: (((( contigo ni ley. ) or ( continuo ni ley. ))) or ((( codigo 2 ley. ) OR ( codigo y ley. ))))~.
• Adding a wildcard symbol may retrieve word variants: (((("contigo ni ley.") or ("continuo ni ley."))) or ((("codigo 2 ley.") OR ("codigo y ley."))))*.
