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.
