Investigate order of Browse by People -> Sort by Count

[erinchambers]

On the Browse by People page (https://cdrhrailsdev.unl.edu/family-letters/en/browse/person.name), the default sort Sort by Count (most first) isn't actually in descending numerical order

For example:

Sort by Count (least first) exhibits the same problem, just in reverse.

It is working for me in my local environment.

I see now that it is out of order. This is the order that it is coming out of Elasticsearch from the query that says sort by doc_count. There is a discrepancy between counts because of nested aggregations. It is sorting on the base doc_count , but the real count (and the one displayed on the side) is in field_to_item.doc_count and the result is out of order relative to that field.
I would either need to change the query to Elasticsearch or re-sort the items in the API app.

I figure out how to change the Elasticsearch query so it sorts nested fields properly, when sorting by count.
