Perhaps you should try some spelling variations:
"programa parallel codigo." » "programa para codigo." (Expand Search)
"programar del codigo." » "programa del codigo." (Expand Search), "programas del codigo." (Expand Search), "programa de codigo." (Expand Search)
"programas a codigo." » "programas y codigo." (Expand Search), "programas de codigo." (Expand Search), "programa la codigo." (Expand Search), "programas al codigo." (Expand Search), "programas el 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: "((\"programa parallel codigo.\") OR (((\"programas a codigo.\") OR (\"programar del codigo.\"))))~".
• Removing quotes may allow a broader search: (( programa parallel codigo. ) OR ((( programas a codigo. ) OR ( programar del codigo. ))))~.
• Adding a wildcard symbol may retrieve word variants: (("programa parallel codigo.") OR ((("programas a codigo.") OR ("programar del codigo."))))*.
