Perhaps you should try some spelling variations:
"historiador" » "historiadores"
"historicorum" » "historiarum", "historico", "historicos"
"historian" » "historia", "historic"
"historians" » "historias", "historics"
"historial" » "historia", "historiae", "historias"

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: (((("historiador" OR "historicorum") OR "historian") OR (("historians" OR "histories") OR ("historicity" OR "historically"))) OR ("historical" OR "historial")).
• Removing quotes may allow a broader search: (((( historiador or historicorum ) or historian ) or (( historians or histories ) or ( historicity or historically ))) or ( historical or historial )).
• Adding a wildcard symbol may retrieve word variants: (((("historiador" or "historicorum") or "historian") or (("historians" or "histories") or ("historicity" or "historically"))) or ("historical" or "historial"))*.
