- Comment out: SearchArtifacts
- Uncomment: Discovery

- Enable the Discovery Indexing Consumer that will update Discovery Indexes on changes to content in XMLUI, JSPUI, SWORD, and LNI in config/dspace.cfg
- 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
- 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
- Add discovery to the list of event.dispatcher.default.consumers
- Check that the port is correct for solr.search.server in config/modules/discovery.cfg
- 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
- If all of your traffic runs over port 80, then you need to remove the port from the URL
- 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.

Configuration files
The configuration for discovery is located in 2 separate files.
- General settings: The discovery.cfg file located in the dspace.dir/config/modules directory.
- User Interface Configuration: The spring-dspace-addon-discovery-configuration-services.xml file is located in dspace.dir/config/spring directory.

General Discovery settings (config/modules/discovery.cfg)
The discovery.cfg file is located in the dspace.dir/config/modules directory and contains following properties:
Property: | search.server |
Example Value: | search.server=http://localhost:8080/solr/search |
Informational Note: | Discovery relies on a SOLR index for storage and retrieval of its information. This parameter determines the location of the SOLR index. |
Property: | search.default.sort.order |
Example Value: | search.default.sort.order=DESC |
Informational Note: | The default sort order for relevance when searching in discovery. This parameter can either be descending (DESC) or ascending (ASC). End-users can change this sort order from the user interface. |
Property: | index.ignore |
Example Value: | index.ignore=dc.description.provenance,dc.language |
Informational Note: | By default, Discovery will include all of the DSpace metadata in its search index. In cases where specific metadata is confidential, repository managers can include those fields by adding them to this comma separated list. |

Structure Summary
Because this file is in XML format, you should be familiar with XML before editing this file. The configurations are organized together in beans, depending on the purpose these properties are used for.
This purpose can be derived from the class of the beans. Here's a short summaries of classes you will encounter throughout the file and what the corresponding properties in the bean are used for.

Default: | There is one configuration by default called defaultConfiguration |
Class: | DiscoverySearchFilter |
Purpose: | Defines that specific metadata fields should be enabled as a search filter |
Default: | dc.title, dc.contributor.author, dc.creator, dc.subject.* and dc.date.issued are defined as search filters |
Class: | DiscoverySidebarFacetConfiguration |
Purpose: | Defines which metadata fields should be offered as a contextual sidebar browse option |
Default: | dc.contributor.author, dc.creator, dc.subject.* and dc.date.issued |
Class: | DiscoverySortConfiguration |
Purpose: | Further specifies the sort options to which a DiscoveryConfiguration refers |
Default: | dc.title and dc.date.issued are defined as alternatives for sorting, other than Relevance (hard coded) |
