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 logs

Solr log files are in $FUSION/var/log/solr.

Accessing the Solr UI

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

Solr documentation

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 searchhub.org.
