Upgrading from Lucene to Solr 4 search

Older versions of Alfresco Content Services use the Lucene search server. You can upgrade from Alfresco Content Services 4.x with the Lucene
 search server to Alfresco Content Services 5.2.6 with the Solr 4 search server.
Note: This documentation refers to Solr 1.4 search subsystem as Solr.
  1. For versions prior to Alfresco Content Services 4.x, upgrade to 4.x and continue to use the Lucene search subsystem as before.
  2. Install and configure Solr on Alfresco Content Services 4.x to track the repository.

    For more information, see Installing and configuring Solr.

  3. Monitor progress using the SUMMARY report.

    http://localhost:8080/solr/admin/cores?action=SUMMARY&wt=xml 
  4. When the Solr index is updated as reported by the SUMMARY report, enable the Solr subsystem and disable the Lucene subsystem.
  5. Follow the instructions for upgrading from Solr to Solr 4 search.
