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)
"programaadas parallel codigo." » "programasaadas parallel codigo." (Expand Search), "programadas parallel codigo." (Expand Search), "programados parallel codigo." (Expand Search), "programada parallel codigo." (Expand Search)

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

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