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