Solr

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.

Configuration for Solr’s Web service is in fusion/apps/jetty/solr.

Solr log files are in fusion/var/log/solr.

With Fusion installed out of the box, you can still access the Solr UI at http://localhost:8983/solr/.

Solr documentation and additional resources are available at http://lucene.apache.org/solr/resources.html.

You can also find plenty of Solr tips and technical discussions in our knowledge base, blog, and webinars. Lucidworks also maintains a search interface to Solr’s community discussions at https://lucidworks.com/resources/searchhub/hub//%2Fp%3Asolr[searchhub.org].
