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