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)
"programasasa parallel codigo." » "programasasasa parallel codigo." (Expand Search), "programadas parallel codigo." (Expand Search), "programas parallel codigo." (Expand Search), "programados 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 (((\"programasasa parallel codigo.\") OR (\"programa de codigo.\"))))~".
• Removing quotes may allow a broader search: (( program _ codigo. ) OR ((( programasasa parallel codigo. ) OR ( programa de codigo. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("program _ codigo.") OR ((("programasasa parallel codigo.") OR ("programa de codigo."))))*.
