Perhaps you should try some spelling variations:
autodidact » autodidacta, autodidakt, autodidactic
autodidacts » autodidactas, autodidakts, autodidactics, autodidactus, autodidacta, autodidactic
autodidaktischen » autodidaktisch, didaktischen, automatischen

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: ( autodidact OR ( autodidacts OR autodidaktischen )).
• Adding a wildcard symbol may retrieve word variants: ( autodidact or ( autodidacts or autodidaktischen ))*.
