Perhaps you should try some spelling variations:
"programa de codigo." » "programa del codigo." (Expand Search), "programa al codigo." (Expand Search), "programasa de codigo." (Expand Search)
"program _ codigo." » "programas _ codigo." (Expand Search)
"programaada parallel codigo." » "programasaada parallel codigo." (Expand Search), "programada parallel codigo." (Expand Search), "programadas parallel codigo." (Expand Search), "programado parallel codigo." (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"program _ codigo.\") OR (((\"programaada parallel codigo.\") OR (\"programa de codigo.\"))))~".
• Removing quotes may allow a broader search: (( program _ codigo. ) OR ((( programaada parallel codigo. ) OR ( programa de codigo. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program _ codigo.") OR ((("programaada parallel codigo.") OR ("programa de codigo."))))*.
