OK, I think now I understand. The source of my confusion was that you said "Discovery sidebar", which I thought meant "Discovery sidebar facets", when you really just meant the sidebar browse indexes. Of course, I shouldn't expect you to recognize the difference just yet.
To explain, you must understand that DSpace originally used only Lucene, not Solr (Discovery is built on top of Solr). It has been using Lucene for browse & search indexes. Browse by Issue Date, Author, Titles - these are browse indexes. You could find them in the advanced search form, too. Browse and search indexes can be configured via dspace.cfg and that is what you did. The index-init and index-update command line launcher commands are used to maintain them. Discovery uses Solr indexes. When you turn on Discovery, Solr is used for search and facets. Facets are what you see in the sidebar on the bottom under the Discovery label. The update-discovery-index is the command-line command. To make things more complicated, XMLUI with Discovery enabled still uses Lucene Browse indexes, but not Lucene Search indexes (instructions to enable Discovery tell you to disable the SearchArtifacts aspect). So both Lucene and Solr is used. Discovery also replaces the old old simple and advanced search form with its own /discover form that uses the Solr index completely. So browse indexes are only used for browsing (in the sidebar). In the JSPUI case, I believe turning on Discovery (introduced in 3.0) replaces Lucene completely. Sorry for the complicated explanation, but this is how the software has been developing. The next step will be to make Discovery default and deprecate Lucene. So, back to your question what discovery.xml is for. This is where you can configure sidebar facets and search filters. Sidebar facets are facets for index fields that you can see e.g. on the homepage. You can see search filters in the search form - where you drill down by Author, Title etc. I hope that clears it up a bit.
