I am searching for an elasticsearch plugin compatible with Elasticsearch 8.19.2 and I am assuming that plugin would be geoserver-2.28.2-elasticsearch-plugin.zip
Can someone point me to a location that I can download an elasticsearch plugin for geoserver that is compatible with Elasticsearch 8.19.2 ?
The elastic search module is a community module so it is not built as part of a release - you can find the latest 2-28-snapshot build here https://build.geoserver.org/geoserver/2.28.x/community-latest/geoserver-2.28-SNAPSHOT-elasticsearch-plugin.zip.
If you need to depend on this module then you can adopt it and work to get it promoted to an extension by contributing time or money to its development
