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