Nationality/Language/Origin
I found out, that a lot of documents can be found by the database, if you choose the proper field for the origin/language/nationality. It's a lot of work, and should be done by the system itself. Sources for the proper origin/language/nationality can be birth documents or the entry itself.
Unfortunately, the selection is "Other" in most cases, maybe a result, that this field was added later.
When adding a new persion, the field is filled according to the country the user is coming. Better the field is set by the respective person entered
