Bugfest. Inventory. Large result list. Sort by Contributors and Publishers are extremely slow (more than 3 min)

Steps to reproduce:

1. Log into FOLIO Bugfest Goldenrod https://bugfest-goldenrod.folio.ebsco.com
2. Go to Inventory, Item segment and filter by Status = Available
3. Check the sort in the url
4. If it doesn't already end with sort=contributors, click on the contributors column (https://bugfest-goldenrod.folio.ebsco.com/inventory?filters=itemStatus.Available&segment=items&sort=contributors)
5. Wait a while for the search to execute
6. Now do sort on Publishers
7. Wait a while for the search to execute

Expected result:
The body of the page should display quickly whether it's sorted by Contributors or Publishers

Actual result:
The body of the page displays after more than 3 minutes.
