1. Enable the Discovery Aspects in the XMLUI by changing the following settings in config/xmlui.xconf
   
   1. Comment out: SearchArtifacts

   2. Uncomment: Discovery

      Code Block
      xml xml
      <xmlui> <aspects> <!-- @deprecated: the Artifact Browser has been devided into ViewArtifacts, BrowseArtifacts, SearchArtifacts <aspect name="Artifact Browser" path="resource://aspects/ArtifactBrowser/" /> --> <aspect name="Displaying Artifacts" path="resource://aspects/ViewArtifacts/" /> <aspect name="Browsing Artifacts" path="resource://aspects/BrowseArtifacts/" /> <!--<aspect name="Searching Artifacts" path="resource://aspects/SearchArtifacts/" />--> <aspect name="Administration" path="resource://aspects/Administrative/" /> <aspect name="E-Person" path="resource://aspects/EPerson/" /> <aspect name="Submission and Workflow" path="resource://aspects/Submission/" /> <aspect name="Statistics" path="resource://aspects/Statistics/" /> <!-- To enable Discovery, uncomment this Aspect that will enable it within your existing XMLUI Also make sure to comment the SearchArtifacts aspect as leaving it on together with discovery will cause UI overlap issues--> <aspect name="Discovery" path="resource://aspects/Discovery/" /> <!-- This aspect tests the various possible DRI features, it helps a theme developer create themes --> <!-- <aspect name="XML Tests" path="resource://aspects/XMLTest/"/> --> </aspects>

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 = versioning, search, browse, eperson, harvester event.dispatcher.default.consumers = versioning, search, browse, discovery, eperson, harvester

   2. Change recent.submissions.count to zero

      Code Block
      #Put the recent submissions count to 0 so that discovery can use it's recent submissions, # not doing this when discovery is enabled will cause UI overlap issues #How many recent submissions should be displayed at any one time #recent.submissions.count = 5 recent.submissions.count = 0

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
   .[dspace]/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. Note that these are only visible when you have items in your repository.
