What is DSpace Discovery

The Discovery Module for the XML user interface enables faceted searching & browsing for your repository.

In a faceted search, a user can filter what they are looking for by grouping entries into a facet, and drill down to find the content they are interested in. 
So instead of user searching: \[ wetland + "dc.author=Mitsch, William J" + dc.subject="water quality" \], theyusers can instead do their initial search, \[ wetland \], and then filter the results by attributes.

Although these techniques are new in DSpace, they might feel familiar from other platforms like Aquabroser or Amazon, where facets help you to select the right product according to facets like price and brand. DSpace Discovery offers very powerful browse and search configurations that were only possible with code customization in the past.

Instructions for enabling Discovery

As with any upgrade procedureupgrade procedure, it is highly recommend that highly recommend that you backup your existing data thoroughly.  This includes cases where upgrading DSpace from 1.6.2 to 1.7.0.  Although Although upgrades in versions of Solr/Lucene do tend to be forwards compatible for forwards compatible for the data stored in the Lucene index, it is always a best practice to backup your dspaceyour dspace.dir/solr/statistics cores to assure no data is lost.

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> <aspect name="Artifact Browser" path="resource://aspects/ArtifactBrowser/" /> <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
   2. Change recent.submissions.count to zero

      Code Block

      #### Event System Configuration #### # 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 #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/dspace-solr-searchmodules/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.
