Perhaps you should try some spelling variations:
"computation dal codigo." » "computation _ codigo." (Expand Search), "computation al codigo." (Expand Search), "computation el codigo." (Expand Search)
"comparacion del codigo." » "comparacion de codigo." (Expand Search)
"programacion a codigo." » "programacion _ codigo." (Expand Search), "programacion de codigo." (Expand Search), "programacion en codigo." (Expand Search), "programacion al codigo." (Expand Search), "programacion 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: "((((\"computation dal codigo.\") OR (\"comparacion del codigo.\"))) OR (\"programacion a codigo.\"))~".
• Removing quotes may allow a broader search: (((( computation dal codigo. ) OR ( comparacion del codigo. ))) OR ( programacion a codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("computation dal codigo.") OR ("comparacion del codigo."))) OR ("programacion a codigo."))*.
