Index admin set relationship using the same field as ActiveFedora-based works

[cjcolvar]

Fixes #5497

The isPartOf_ssim field is used when searching for works belonging to an admin set.

hyrax/app/presenters/hyrax/admin_set_presenter.rb

Line 11 in d628b58

Hyrax::SolrService.count("{!field f=isPartOf_ssim}#{id}")

Future work:

• write a feature test
• change the hardcoded isPartOf_ssim in the line referenced above and the other occurrence in that presenter to use the configuration Hyrax.config.admin_set_predicate.qname.last which is used in the search builder
  

  hyrax/app/search_builders/hyrax/admin_admin_set_member_search_builder.rb

  Line 27 in b034218

  solr_parameters[:fq] << "{!term f=#{Hyrax.config.admin_set_predicate.qname.last}_ssim}#{collection.id}"

Is there an issue for the suggested future work, especially the change of hardcoded isPartOf_ssim to use the config instead?

[cjcolvar]

I didn't make an issue yet. I could just push the change to this PR quickly.

[cjcolvar]

I think I was hesitant before because I don't really like the configuration but this change at least makes it consistent and it can be cleaned up in the future.

Thanks for the update to use the config. We can re-evaluate the config as a whole, but I know it was put in place intentionally to address apps that needed to use a different predicate, because iPartOf was already in use for a different purpose.
