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