Comment: Update configs based on Commons Config

...

The legacy search engine (based on Apache Lucene) and legacy Browse system (based on database tables) have been removed from DSpace 6.0 or above. Instead, DSpace now only uses Discovery for all Search/Browse capabilities.

In addition, to support the new Configuration options, all of the Discovery configurations in discovery.cfg have been prefixed with "discovery." (see configuration below).

DSpace 5.0

The new JSPUI-only tag cloud facet feature is disabled by default. In order to enable it, you will need to set up the corresponding processor that the PluginManager will load to actually perform the tag cloud query on the relevant pages. This is configured in the dspace.cfg configuration file using the following properties:

...

The discovery.cfg file is located in the [dspace-install-dir]/config/modules directory and contains following properties. Any of these properties may be overridden in your local.cfg (see Configuration Reference):

Property:

discovery.search.server

Example Value:

discovery.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:

discovery.index.authority.ignore[.field]

Example Value:

discovery.index.authority.ignore=true

discovery.index.authority.ignore.dc.contributor.author=false

Informational Note:

By default, Discovery will use the authority information in the metadata to disambiguate homonyms. Setting this property to false will make the indexing process the same as the metadata  doesn't include authority information. The configuration can be different on a field (<schema>.<element>.<qualifier>) basis, the property without field set the default value.

Property:

discovery.index.authority.ignore-prefered[.field]

Example Value:

discovery.index.authority.ignore-prefered=true

discovery.index.authority.ignore-prefered.dc.contributor.author=false

Informational Note:

By default, Discovery will use the authority information in the metadata to query the authority for the prefered preferred label. Setting this property to false will make the indexing process the same as the metadata  doesn't include authority information (i.e. the prefered preferred form is the one recorded in the metadata value). The configuration can be different on a field (<schema>.<element>.<qualifier>) basis, the property without field set the default value. If the authority is a remote service, disabling this feature can greatly improve performance.

Property:

discovery.index.authority.ignore-variants[.field]

Example   Value:

discovery.index.authority.ignore-variants=true

discovery.index.authority.ignore-variants.dc.contributor.author=false

Informational Note:

By default, Discovery will use the authority information in the metadata to query the authority for variants. Setting this property to false will make the indexing process the same, as the metadata  doesn't include authority information. The configuration can be different on a per-field (<schema>.<element>.<qualifier>) basis, the property without field set the default value. If authority is a remote service, disabling this feature can greatly improve performance.

The discovery.xml file is located in the [dspace-install-dir]/config/spring/api directory.
