Dear Mark, Is there a difference in the automatic re-indexing that is triggered by the existence of the `dspace/solr/search/conf/reindex.flag` and a manually triggered `dspace index-discovery -b`? After my database migration was completed I started Tomcat and then immediately triggered a manual re-indexing. I lost a few hours investigating the cause of this, only to stumble on the fact that the "automatic" re-indexing apparently does something differently—the effects of which are only visible if the "automatic" re-indexing actually completes without interruption! Very strange...
