Perhaps you should try some spelling variations:
"autodidacta" » "autodidactic", "autodidakt"
"autodidactus" » "autodidactic", "autodidakt"
"autodidakten" » "autoritaten", "autodidaktischen"
"autodidaktas" » "autodidactas", "autodidatas", "autodidakt"
"autodidactics" » "autodidactic", "autodidacticism", "autodidacts"

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