• The words AND, OR and NOT may confuse the search; try adding quotes: "ergebnisse ((der mathematical) OR (her mathematical)) und ihre grenzgebieten. 2. folge, a series of modern survey in mathematics".
• Adding a wildcard symbol may retrieve word variants: ergebnisse ((der mathematical) OR (her mathematical)) und ihre grenzgebieten. 2. folge, a series of modern survey in mathematics*.
