Solr is the search platform that powers Fusion. There are multiple aspects to Fusion’s use of Solr:

  • Fusion components manage Solr search and indexing and provide analytics over these collections. Fusion’s analytics components depend on aggregations over information which is stored in a Solr collection.

  • Fusion collections are all Solr collections.

  • Application data is stored as one or more Solr collections.

  • Fusion’s own logs are stored as Solr collections.

  • A few Fusion service APIs use Solr as a backing store, notably Parameter Sets.

Solr configuration

Fusion requires that Solr run with SolrCloud enabled.
