Perhaps you should try some spelling variations:
"autodidacts" » "autodidactus", "autodidacta", "autodidactic"
"autodidactaic" » "autodidactic", "autodidacta", "autodidactas"
"autodidactics" » "autodidactic", "autodidacticism", "autodidactus"

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