Subject Delete all, index all, end up with 1 segment with 50% deletes
Date Tue, 27 Nov 2018 12:29:32 GMT

A background  batch process compiles a data set, when finished, it sends a delete all to its
target collection, then everything gets sent by SolrJ, followed by a regular commit. When
inspecting the core i notice it has one segment with 9578 documents, of which exactly half
are deleted. 

That Solr node is on 7.5, how can i encourage the merge scheduler to do its job and merge
away all those deletes?
