Solr is an open source enterprise search server based on the Lucene Java search library with XML/HTTP and JSON APIs. Documents are indexed by sending them formatted in XML via HTTP to a Solr instance. Queries are sent as HTTP GET request to the server and returned to the client as XML/JSON results.

The main features are:

  • Advanced full-text search capabilities
  • Optimised for high-volume Web traffic
  • Standards-based open interfaces – XML and HTTP
  • Comprehensive HTML administration interfaces
  • Server statistics exposed over JMX for monitoring
  • Scalability – efficient replication to other Solr search servers
  • Flexible and adaptable through XML configuration
  • Extensible plug-in architecture
  • Solr uses the Lucene Search Library and extends it

For more information about Solr, please see the Solr wiki.

The Solr version you find here uses a specifically defined index as well as a special XML output for requests generated via Carrot4MAREC.
