Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidakt", "autodidactic"
"autodidactus" » "autodidactaus", "autodidaktus", "autodidacticus", "autodidactic", "autodidacta", "autodidakten"
"autodidacts" » "autodidactas", "autodidakts", "autodidactics", "autodidacta", "autodidactic", "autodidakt"
"autodidakts" » "autodidakt", "autodidakten", "autodidactas"

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 "autodidactus") OR (("autodidacts" OR "autodidakts") OR "autodidaktisch")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"autodidact\" or \"autodidactus\") or ((\"autodidacts\" OR \"autodidakts\") or \"autodidaktisch\"))".
• Removing quotes may allow a broader search: (( autodidact or autodidactus ) or (( autodidacts OR autodidakts ) or autodidaktisch )).
• Adding a wildcard symbol may retrieve word variants: (("autodidact" or "autodidactus") or (("autodidacts" OR "autodidakts") or "autodidaktisch"))*.
