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.

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.

index.authority.ignore=true

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

By default, Discovery will use the authority information in the metadata to disambiguate homonymous. 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.

index.authority.ignore-prefered=true

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

By default, Discovery will use the authority information in the metadata to query the authority for the prefered 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 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 disable , disabling this feature can greatly improve a lot performance.

index.authority.ignore-variants=true

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

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 field (<schema>.<element>.<qualifier>) basis, the property without field set the default value. If the authority is a remote service disable , disabling this feature can greatly improve a lot performance.

Purpose:

Defines the mapping between separate Discovery configurations and individual collections/communities

Default:

All communities, collections and the homepage (key=default) are mapped to defaultConfiguration

Purpose:

Groups configurations for sidebar facets, search filters, search sort options and recent submissions

Default:

There is one configuration by default called defaultConfiguration

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

Purpose:

Defines which metadata fields should be offered as a contextual sidebar browse options, each of these facets has also got to be a search filter

Default:

dc.contributor.author, dc.creator, dc.subject.* and dc.date.issued

Purpose:

Defines which metadata fields contain hierarchical data and should be offered as a contextual sidebar option

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)

Purpose:

Defines which metadata fields can contain hit highlighting & search snippets

Default:

dc.title, dc.contributor.author, dc.subject, dc.description.abstract & full text from text files.
