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

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