• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"program _ codigo.\") OR (\"programaaaacion al codigo.\"))) OR (\"programacion paralela codigo.\"))~".
• Removing quotes may allow a broader search: (((( program _ codigo. ) OR ( programaaaacion al codigo. ))) OR ( programacion paralela codigo. ))~.
• Adding a wildcard symbol may retrieve word variants: (((("program _ codigo.") OR ("programaaaacion al codigo."))) OR ("programacion paralela codigo."))*.
