Perhaps you should try some spelling variations:
"programacion paralela codigo." » "programacion para codigo." (Expand Search), "programacion grafica codigo." (Expand Search)
"programa drag codigo." » "programa de codigo." (Expand Search), "programa del codigo." (Expand Search), "programa para codigo." (Expand Search)
"computational _ codigo." » "computacionales _ codigo." (Expand Search), "computacion _ 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: (((("computational _ codigo.") OR ("programa drag codigo."))) OR ("programacion paralela codigo."))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"computational _ codigo.\") OR (\"programa drag codigo.\"))) OR (\"programacion paralela codigo.\"))".
• Removing quotes may allow a broader search: (((( computational _ codigo. ) OR ( programa drag codigo. ))) OR ( programacion paralela codigo. )).
• Adding a wildcard symbol may retrieve word variants: (((("computational _ codigo.") OR ("programa drag codigo."))) OR ("programacion paralela codigo."))*.
