When you install Alfresco Content Services
5.2.6 using the setup wizard
(installer), Solr 4 is installed by default. For additional search functionality, you can install
Alfresco Search Services with Solr 6 which introduces additional
features, including new sharding methods and sharding with SSL. It can optionally be configured
with or without SSL.
You may choose to secure Alfresco Search Services by installing Solr 6 with SSL enabled.
Note: When choosing to secure Solr 6
with SSL, be aware that there is a known issue when using Solr 6 where the SSL truststore and
keystore passwords are visible as plain text in the Solr 6 process arguments. Alfresco recommends that you ensure
the server running Solr 6 is security
hardened and access is restricted to admin users only. For more information, see https://issues.apache.org/jira/browse/SOLR-8897.
Alfresco Search Services 1.2 supports all Alfresco Content Services 5.2.6 certified platforms and components. For more information, see Supported Platforms.
