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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("codigo da ley.") OR ("codigos 1 ley."))) OR ((("codigo 2 ley.") OR ("codigo a les."))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"codigo da ley.\") OR (\"codigos 1 ley.\"))) OR (((\"codigo 2 ley.\") OR (\"codigo a les.\"))))".
• Removing quotes may allow a broader search: (((( codigo da ley. ) OR ( codigos 1 ley. ))) OR ((( codigo 2 ley. ) OR ( codigo a les. )))).
• Adding a wildcard symbol may retrieve word variants: (((("codigo da ley.") OR ("codigos 1 ley."))) OR ((("codigo 2 ley.") OR ("codigo a les."))))*.
