Configuring the Solr 4 search service

The topic describes the properties for configuring the Solr 4 search service.

1. Open the Admin Console.
2. In the Repository Services section, click Search Service.

   You see the Search Service page.

3. In the Search Service section, select Solr 4 from the Search Service In Use list.
   Important: The Solr 1 option should be used only for migration to Solr 4.
4. Set the Solr 4 search service properties:

   Solr search property	Example setting	What is it?
   Content Tracking Enabled	Yes	This specifies that Solr 4 can still track with the No Index search enabled. This setting can be used to disable Solr 4 tracking by separate Solr instance(s) configured to track this server.
   Solr Port (Non-SSL)	8080	This specifies the application server's http port (non-secure) on which Solr 4 is running. This is only used if Solr 4 is configured to run without secure communications.
   Solr base URL	/solr4	This specifies the base URL for the Solr 4 web application.
   Solr Hostname	localhost	This specifies the hostname on which the Solr 4 server is running. Use localhost if running on the same machine.
   Solr SSL Port	8443	This specifies the application server's https port on which Solr 4 is running.
   Auto Suggest Enabled	0	This specifies that the Solr 4 auto-suggest feature is enabled. This feature presents suggestions of popular queries as a user types their query into the search box or text box.
   Indexing in Progress	No	This specifies if Solr 4 is currently indexing outstanding transactions.
   Last Indexed Transaction	17	This specifies the transaction ID most recently indexed by Solr 4.
   Approx Index Time Remaining	0 Seconds	This specifies the estimated time that Solr 4 will take to complete indexing the current outstanding transactions.
   Disk Usage (GB)	0.001748	This specifies the disk space used by the latest version of the Solr 4 index. Allow at least double this value for background indexing management.
   Index Lag	0 s	This specifies the time that indexing is currently behind the repository updates.
   Approx Transactions to Index	0	This specifies the estimated number of outstanding transactions that require indexing.
   Memory Usage (GB)	0	This specifies the current memory usage. The value may vary due to transient memory used by background processing.
   Indexing in Progress	No	This specifies if Solr 4 is currently indexing outstanding transactions.
   Last Indexed Transaction	17	This specifies the transaction ID most recently indexed by Solr 4.
   Approx Index Time Remaining	0 Seconds	This specifies the estimated time that Solr 4 will take to complete indexing the current outstanding transactions.
   Disk Usage (GB)	0.000034	This specifies the disk space used by the latest version of the Solr 4 index. Allow at least double this value for background indexing management.
   Index Lag	0 s	This specifies the time that indexing is currently behind the repository updates.
   Approx Transactions to Index	0	This specifies the estimated number of outstanding transactions that require indexing.
   Memory Usage (GB)	0	This specifies the current memory usage. The value may vary due to transient memory used by background processing. The value does not include Lucene related caches.
   Backup Location (Main Store)	${dir.root}/solr4Backup/SkyVault	This specifies the location where the index backup for the main WorkspaceStore is stored on the Solr 4 server.
   Backup Cron Expression (Main Store)	0 0 2 * * ?	This specifies a unix-like expression, using the same syntax as the cron command, that defines when backups occur. The default value is 0 0 2 * * ? meaning the backup is performed daily at 02.00.
   Backups To Keep (Main Store)	3	This specifies the number of backups to keep (including the latest backup).
   Backup Location (Archive Store properties)	${dir.root}/solr4Backup/archive	This specifies the location where the index backup for ArchiveStore is stored on the Solr 4 server.
   Backup Cron Expression (Archive Store properties)	0 0 4 * * ?	This specifies a unix-like expression, using the same syntax as the cron command, that defines when backups occur. The default value is 0 0 4 * * ? meaning the backup is performed daily at 04.00.
   Backups To Keep (Archive Store properties)	3	This specifies the number of backups to keep (including the latest backup).
   CMIS Query	Use database if possible	This specifies the default mode which defines if and when the database should be used to support a subset of the CMIS Query Language.
   SkyVault Full Text Search	Use database if possible	This specifies the default mode which defines if and when the database should be used to support a subset of the SkyVault Full Text Search.

   Note: In the Transactional Query Options section, it is possible to select Hybrid (Solr and Database) for both CMIS Query and SkyVault Full Text Search. This option is an unsupported experimental option and must not be used on production systems.
