Configuration to delete/ reset the SOLR index
As discussed in the meeting today with @ralf.klammer @arnevogt @MarkusKonk , nothing urgent but use this issue here to keep track.
Problem: Sometime remote resources are being deleted from the KH. In order to reflect this in the OneStop4All index, best way is to build the index from scratch (as long is this as fast as it is at the moment).
Option 1: Configure the infrastructure setup to e.g. once per week remove the solr volume and re-index from scratch (additionally to daily incremental indexing jobs)
Option 2: Configure within the Onestop4all-harvester package an option to reset the solr index via its API
