Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidacts", "autodidakt"
"autodidactaic" » "autodidactaaic", "autodidactsaic", "autodidaktaic", "autodidactic", "autodidacta", "autodidactas"
"autodidakten" » "autoritaten", "autodidaktischen"

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: (("autodidact" OR "autodidactaic") OR "autodidakten").
• Removing quotes may allow a broader search: (( autodidact or autodidactaic ) or autodidakten ).
• Adding a wildcard symbol may retrieve word variants: (("autodidact" or "autodidactaic") or "autodidakten")*.
