Perhaps you should try some spelling variations:
"programacion pardel codigo." » "programacion paralela codigo." (Expand Search), "programacion del codigo." (Expand Search), "programacion para codigo." (Expand Search)
"programada pardel codigo." » "programada del codigo." (Expand Search)
"programas _ codigo." » "programa _ 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: "((\"programas _ codigo.\") OR (((\"programada pardel codigo.\") OR (\"programacion pardel codigo.\"))))~".
• Removing quotes may allow a broader search: (( programas _ codigo. ) OR ((( programada pardel codigo. ) OR ( programacion pardel codigo. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("programas _ codigo.") OR ((("programada pardel codigo.") OR ("programacion pardel codigo."))))*.
