Perhaps you should try some spelling variations:
"programa del codigo." » "programa de codigo." (Expand Search), "programas de codigo." (Expand Search), "programasa del codigo." (Expand Search)
"program _ codigo." » "programas _ codigo." (Expand Search)
"programaaaas parallel codigo." » "programasaaaas parallel codigo." (Expand Search), "programadas parallel codigo." (Expand Search), "programaticas parallel codigo." (Expand Search), "programas 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 (((\"programaaaas parallel codigo.\") OR (\"programa del codigo.\"))))~".
• Removing quotes may allow a broader search: (( program _ codigo. ) OR ((( programaaaas parallel codigo. ) OR ( programa del codigo. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program _ codigo.") OR ((("programaaaas parallel codigo.") OR ("programa del codigo."))))*.
