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