Solr integration in Hippo CMS
The Delivier Tier supports Solr integration. With Solr integration, it is possible to seamlessly use Delivery Tier its ContentBeans from Solr search results, where the beans can be backed by JCR based Hippo Repository Documents, or from any other source, eg external sources fetched over http or sources from other CMS's or DMS's.
A presentation about some background reasons for the Solr integration can be found here:
