Perhaps you should try some spelling variations:
"herr apparent / early works to 1800" » "heirs apparent / early works to 1800", "very apparent / early works to 1800", "every apparent / early works to 1800"
"her apparent / early works to 1800" » "heirs apparent / early works to 1800", "very apparent / early works to 1800", "der apparenz / early works to 1800"
"heir apparent / early works to 1800" » "hear apparent / early works to 1800", "hair apparent / early works to 1800"

Try widening your search to All Fields.

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: (("her apparent / early works to 1800") OR ((("heir apparent / early works to 1800") OR ("herr apparent / early works to 1800")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"her apparent / early works to 1800\") or (((\"heir apparent / early works to 1800\") OR (\"herr apparent / early works to 1800\"))))".
• Removing quotes may allow a broader search: (( her apparent / early works to 1800 ) or ((( heir apparent / early works to 1800 ) OR ( herr apparent / early works to 1800 )))).
• Adding a wildcard symbol may retrieve word variants: (("her apparent / early works to 1800") or ((("heir apparent / early works to 1800") OR ("herr apparent / early works to 1800"))))*.
