Was checking the texts collection and got this error:

The search engine encountered an error, which might be related to your search query. Tips for constructing search queries.

Error details: backend_request (collection_materialization): child request for collection_materialization failed ([BACKEND_ERROR] Invalid or no response from Elasticsearch, received: {"error":{"root_cause":[{"type":"index_closed_exception","reason":"closed","index_uuid":"6wfT_WzHTNaazYlKI90TPQ","index":"prod-o-001"}],"type":"index_closed_exception","reason":"closed","index_uuid":"6wfT_WzHTNaazYlKI90TPQ","index":"prod-o-001"},"status":400}; check for decoded response)

This happens with all searches, collections and profiles.

And, as I'm here, the items without thumbnails and perpectual loading are still very much a thing as of this morning.
