Filters and Dated Places
I've come across a bug or complication, I'm afraid, relating to filters acting on Dated Places.
I created a single-stage filter in my db for People born in Germany {People with the <birth data>: Place="Germany"}
The individuals selected by the filter include a person who was born in Schleswig-Holstein in 1854. At this period it was part of Denmark; Germany itself did not exist before 1871.
A similar filter for people born in Denmark {People with the <birth data>: Place="Denmark"} fails to show this person.
The Place hierarchy for Schleswig-Holstein in the database is Schleswig-Holstein< Denmark before 1865; <Prussia from 1867 to 1871; <Germany after 1871. The name Germany is set valid after 1871.
