Installing Solr Search
Solr is not bundled with Magento and must be installed separately by your hosting firm or system administrator. Although Magento does not provide support for configuring Solr server we do provide Solr configuration and schema files to help your hosting firm or system administrator with the initial server configuration. Please contact the Magento Support team for assistance.
When you enable and configure Solr, quick search and advanced search are redirected to the Solr server, although the results appear in the same way as they would if using the default MySQL-based search.
During the installation process, you must specify the host name, port, and the password to connect to the server where Solr search engine is installed. You will need to complete the initial part of the configuration before fine-tuning the Solr features.
