    Description

      After some research related to MDL-53281, I've found it's generally not preferred to optimize the solr database after every indexing run. Generally you only want to do it a at most a few times a day. It's quite intensive on the solr server, and ~doubles the index size while it is happening.

      Optimize should likely be moved into it's own task, separate solr task from the index task.
