Perhaps you should try some spelling variations:
d functionalanalysis » _ functionalanalysis, d funktionalanalysis, b funktionalanalysis
8 funktionalanalysis » b funktionalanalysis, _ functionalanalysis, der funktionalanalysis
v funktionalanalysis » b funktionalanalysis, _ functionalanalysis, der funktionalanalysis

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: %((d functionalanalysis) OR (((8 funktionalanalysis) OR (v funktionalanalysis))))%22.
• Adding a wildcard symbol may retrieve word variants: %((d functionalanalysis) or (((8 funktionalanalysis) or (v funktionalanalysis))))%22*.
