Hey everyone,
I have elasticsearch 8.10.4 running on my server and the in the elasticsearch app (v27.0.4) is set to the same settings as the elasticsearch.yml. Nevertheless I am not able to get any search results by elasticsearch.
I indexed the files with “occ fulltextsearch:index” then I ran “occ fulltextsearch:test” and it crashed by trying to search the basic keywords:
root@xxx:# /opt/plesk/php/8.2/bin/php /var/www/vhosts/xxx/httpdocs/nextcloud/occ fulltextsearch:test
.Testing your current setup:

In Test.php line 676:

Im running on Ubuntu 20.04.6 LTS, Nextcloud 27.1.2 with Full text search v27.0.2, Full text search - Elasticsearch Platform v27.0.4 and Full text search - Files v27.0.1.
I also tried to reinstall elasticsearch on the server, but that didn’t solve the problem. It worked on Ubuntu 18.04 and elasticsearch 7.17.14.
I am running out of ideas how to fix it and didn’t found any topic about it. Any help is apprechiated. Thank you!
