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