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