Perhaps you should try some spelling variations:
modern surveys » modern purveyors, modern surgery, models survey
modern survey » modern surgery, models survey, model survey
oder surveys » der surveys, other surveys, cover surveys
mathematik » mathematical

You may be able to get more results by adjusting your search query.

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