Perhaps you should try some spelling variations:
neologismus » neologisms, neologismsus, geologistus
neologism » neologisms, geologist
biologismus » biologists, biologisches
biologischen » biologische, soziologischen

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: ((neologismus OR neologism) OR (biologismus OR biologischen)).
