Solr field candidates to go away

[ndushay]

Based on looking through indexing code. Before removing any:

• do a global search in dor_indexing_app for the exact field name, and possibly for the string before the fieldtype prefix
• ditto for argo
• for sul_dlss github organization repos
• hydra_etd and google-books (private repos)

Candidates:

• [x] sw_author_tesim - cleanup after fixing author search (sul-dlss/argo/issues/4231) used for display in Argo
  • [x] new field author_display_ss sul-dlss/dor_indexing/pull/21 - populating as of 2/16/24
  • [x] new field populated 2/21/24
  • [x] replaced in consuming code (argo only) sul-dlss/argo/pull/4324
  • [x] old field no longer indexed after argo deployed to prod https://github.com/sul-dlss/dor_indexing/pull/33
• [x] objectId_tesim - um ... can't we use id or some other indexing of bare_druid and prefixed_druid ?
  • [x] new fields - sul-dlss/dor_indexing/pull/17 - populating as of 2/16/24
  • [x] new field populated 2/21/24
  • [x] replaced in consuming code (see sul-dlss/dor_indexing_app/issues/1031)
  • [x] old field no longer indexed after consuming code deployed to prod sul-dlss/dor_indexing/pull/34
• [ ] object_label_tesim ? See sul-dlss/argo/issues/4262
• [x] source_id_ssim - cleanup after PRs #1038, sul-dlss/argo/pull/4256 and sul-dlss/argo/issues/4194 and #1084
• [x] exploded_tag_ssim - cleanup after sul-dlss/argo/pull/4206, sul-dlss/argo/issues/4187
• [x] metadata_format_ssim - not used sul-dlss/dor_indexing/pull/20/
• [x] metadata_source_ssi vs metadata_source_ssim --see #946 and #947 (done?)
• [x] solr_doc["#{prefix}_tag_ssim"] in admintags line 33 ... is this to make the tag searchable? sul_tag_ssim?? -- address with code refactor and better comments
• [x] various identifier flavors; besides bare and prefixed for each of druid, barcode, sourceid, folio instance id, previous ils ids, doi ... what else? do we need all these?
  • see objectId_tesim above

[ndushay]

For each field to be deleted:

• [ ] search argo for any usage
• [ ] search dor_services_app for any usage
• [ ] search dor_indexing_app for any usage
• [ ] search rest of infra apps for any usage (?)
• [ ] search dor_indexing gem for any usage
• [ ] ensure we no longer index to it in dor_indexing gem
• [ ] watch it being depopulated in solr admin schema interface

closing this; all is done except remaining uses of obj_label and that is ticketed as sul-dlss/argo#4262
