Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidacts", "autodidactus"
"autodidactaic" » "autodidactaaic", "autodidactsaic", "autodidactusaic", "autodidacta", "autodidactas", "autodidactus"
"autodidactic" » "autodidactaic", "autodidactsic", "autodidactusic", "autodidaktisch", "autodidakten"
"autodidakt" » "autodidakten"

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