/**
* The adminServer is just a reference to a SolrServer component for connecting to Solr. In newer
* versions of Solr, 4.4 and beyond, auto discovery of cores is
* provided. When using a stand-alone server or server cluster,
* the admin server, for swapping cores, is a different URL. For example,
* one needs to use http://solrserver:8983/solr, which formerly acted as the admin server
* AND as the primary core. As of Solr 4.4, one needs to specify the cores separately:
* http://solrserver:8983/solr/primary and http://solrserver:8983/solr/reindex,
* and use http://solrserver:8983/solr for swapping cores.
*
* By default, this method attempts to return an admin server if configured. Otherwise,
* it returns the primary server if the admin server is null, which is backwards compatible
* with the way that BLC worked prior to this change.
