Perhaps you should try some spelling variations:
historiae » historian, historiker, historic, historice
historie » historic, historian
histories » historics, historians
historikerin » historikern, historiker, historikers
historicns » historicos, historicas, historiens
historians » historicns
historia » historic

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: (((( (historiae OR historie) OR historikerin ) OR (historians OR historicns) ) OR historical ) OR ( historia OR histories ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((( (historiae OR historie) or historikerin ) or (historians or historicns) ) or historical ) or ( historia or histories ))*".
