• If you are trying to use Boolean operators, they must be ALL CAPS: %ergebnisse der (mathematik OR mathematical) und ihre grenzgebiete. 2. folge%c a series of ((((modern surveys) OR (((oder surveys) OR (der surveys))))) OR (modern survey)) in mathematics%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%ergebnisse der (mathematik or mathematical) und ihre grenzgebiete. 2. folge%c a series of ((((modern surveys) or (((oder surveys) OR (der surveys))))) or (modern survey)) in mathematics%22".
• Adding a wildcard symbol may retrieve word variants: %ergebnisse der (mathematik or mathematical) und ihre grenzgebiete. 2. folge%c a series of ((((modern surveys) or (((oder surveys) OR (der surveys))))) or (modern survey)) in mathematics%22*.
