Well, still bugged but at least some neat features are here !
This update resets the current setup of your Nextant. Meaning that, after upgrading, you will need to visit the administration page to configure your Nextant (again), and index your files (again).
It is recommended to delete/recreate the core from your Solr Servlet before configuring your Nextant.
$ sudo -u solr /opt/solr/bin/solr delete -c nextant $ sudo /etc/init.d/solr restart $ sudo -u solr /opt/solr/bin/solr create -c nextant
Note: Indexing requiert a descent amount of ressources. I am aware that some of you are running nextcloud on single-board computer (Raspberry Pi, oDroid, ...) and I have no idea if Solr is running fine on that kind of equipment.
