Perhaps you should try some spelling variations:
"autodidactus" » "autodidactic", "autodidacta", "autodidakten"
"autodidakt" » "autodidakten"
"autodidacts" » "autodidacta", "autodidactic", "autodidakten"
"autodidactas" » "autodidacta", "autodidactes", "autodidactos"
"autodidactics" » "autodidactic", "autodidacticism", "autodidactes"

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