Perhaps you should try some spelling variations:
"autodidact" » "autodidacta", "autodidakt", "autodidactic"
"autodidacts" » "autodidactas", "autodidakts", "autodidactics", "autodidactus", "autodidacta", "autodidactic"
"autodidactics" » "autodidactaics", "autodidaktics", "autodidacticics", "autodidactic", "autodidactus", "autodidactas"
"autodidactaics" » "autodidactaaics", "autodidaktaics", "autodidacticaics", "autodidactic", "autodidactas", "autodidacta"
"autodidacticism" » "autodidactaicism", "autodidakticism", "autodidacticicism", "autodidactic"

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