1. Enable the Discovery Search processor in the by changing the following settings in config/dspace.cfg
   
   1. Comment out: org.dspace.app.webui.search.LuceneSearchRequestProcessor

   2. Uncomment: org.dspace.app.webui.discovery.DiscoverySearchRequestProcessor

      Code Block
      xml xml
      plugin.single.org.dspace.app.webui.search.SearchRequestProcessor = \ org.dspace.app.webui.discovery.DiscoverySearchRequestProcessor

2. Enable the Discovery Indexing Consumer that will update Discovery Indexes on changes to content in XMLUI, JSPUI, SWORD, and LNI in config/dspace.cfg
   

   1. Add discovery to the list of event.dispatcher.default.consumers

      Code Block
      # default synchronous dispatcher (same behavior as traditional DSpace) event.dispatcher.default.class = org.dspace.event.BasicDispatcher #event.dispatcher.default.consumers = search, browse, eperson, harvester event.dispatcher.default.consumers = search, browse, discovery, eperson, harvester

      Note
      As it is not possible in JSPUI to use both search provider (Lucene and Discovery),  it is generally more appropriate, but not required, to remove the "search" consumer from the list above. The "browse" consumer can be removed as well if you configure the Browse System to use SOLR/Discovery as its backend (see Defining the Storage of the Browse Data)

   2. Enable facet showing in the Repository, Communities and Collections home pages

      Code Block

      plugin.sequence.org.dspace.plugin.CommunityHomeProcessor = \ org.dspace.app.webui.components.RecentCommunitySubmissions,\ org.dspace.app.webui.discovery.SideBarFacetProcessor plugin.sequence.org.dspace.plugin.CollectionHomeProcessor = \ org.dspace.app.webui.components.RecentCollectionSubmissions,\ org.dspace.app.webui.discovery.SideBarFacetProcessor plugin.sequence.org.dspace.plugin.SiteHomeProcessor = \ org.dspace.app.webui.discovery.SideBarFacetProcessor

      Note
      Please note that JSPUI instead of XMLUI still rely (in contrast to XMLUI) still relies on the Browse Engine to show "recent submissions". The browse engine can be configured to use SOLR/Discovery as its backend (see Defining the Storage of the Browse Data)

   3. Enable a JSON endpoint to provide autocomplete feature in the search form

      Code Block
      plugin.named.org.dspace.app.webui.json.JSONRequest = \ org.dspace.app.webui.discovery.DiscoveryJSONRequest = discovery

3. Check that the port is correct for solr.search.server in config/modules/discovery.cfg
   

   1. If all of your traffic runs over port 80, then you need to remove the port from the URL

      Code Block
      ##### Search Indexing ##### solr.search.server = http://localhost/solr/search

4. From the command line, navigate to the dspace directory and run the command below to index the content of your DSpace instance into Discovery.

   Code Block
   ./bin/dspace update-discovery-index

   Panel
   NOTE: This step may take some time if you have a large number of items in your repository.

5. Verify that you can see the Sidebar Facets on your DSpace homepage or that empty search query will return all the repository content. Note that these are only visible when you have items in your repository.
