Perhaps you should try some spelling variations:
"autodidacta" » "autodidactic", "autodidactus", "autodidakten"
"autodidactaics" » "autodidacticics", "autodidactusics", "autodidaktenics", "autodidactic", "autodidactas", "autodidacticism"
"autodidakt" » "autodidakten"
"autodidacts" » "autodidactus", "autodidactic", "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: (("autodidacta" OR "autodidakt") OR ("autodidacts" OR "autodidactaics")).
• Removing quotes may allow a broader search: (( autodidacta or autodidakt ) or ( autodidacts or autodidactaics )).
• Adding a wildcard symbol may retrieve word variants: (("autodidacta" or "autodidakt") or ("autodidacts" or "autodidactaics"))*.
