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

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