Perhaps you should try some spelling variations:
"autodidactus" » "autodidacta", "autodidakten", "autodidakt"
"autodidacts" » "autodidacta", "autodidakt", "autodidakten"
"autodidactic" » "autodidaktisch", "autodidakten", "autodidakt"

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: ("autodidactus" OR ("autodidacts" OR "autodidactic")).
• Removing quotes may allow a broader search: ( autodidactus or ( autodidacts or autodidactic )).
• Adding a wildcard symbol may retrieve word variants: ("autodidactus" or ("autodidacts" or "autodidactic"))*.
