@al-niessner I'll test it shortly

Confirmed correct via comparison of branches main and issue_343

~$ curl -s -X 'GET'   'http://localhost:8080/products?limit=100&start=0'   -H 'accept: *' | jq .summary.hits
10000
~$ curl -s -X 'GET'   'http://localhost:8080/products?limit=100&start=0'   -H 'accept: *' | jq .summary.hits
