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