Nextcloud 28 and Fulltext Search

Yesterday I updated by mistake from 27.1.4 to 28.0.0

Unfortunately now the Fulltext Search is not woring any longer, even the search fields on the left are not shown anymore. Is this known, and how can I fix it?

Same here - and so far I don’t know how to fix that either.

Solved for me: Elasticsearch 8 did not run and I had to start it again. I am not sure if this was caused by the upgrade to Nextcloud 28, but it works now.
