If used, the automatic index cleanup rules are run once per day. To configure automatic history deletion:
In the Administration Options menu, go to Projects > Your Project > Indexing > History tab.
Set the following:
Minimum inactive indexes—You must have at least the specified number of inactive indexes before any index is automatically deleted.
Note: Active indexes are never automatically deleted.
X most recently indexed—Retain this number from the most recently created indexes.
Indexed in last X days—Retain indexes created after the specified number of days in the past.
If neither the “X most recently indexed” nor the “Indexed in last X days” rule is selected, no indexes are deleted.
Click the Save Rules button.
When indexes are automatically removed, both the index files and the related event histories are deleted.
An index will not be deleted if there is another sync task not scheduled for deletion that has a reference to that index.
By default, cleanup rules are run 30 minutes after Search starts up, and every 24 hours after that. This can be configured in the schedule property of the /atg/searchadmin/repository/service/IndexCleanupService Nucleus component. You can run the cleanup manually at any time using the Dynamo Admin UI (see the ATG Installation and Configuration Guide for information on this tool). Go to /atg/searchadmin/repository/service/IndexCleanupService, and invoke the cleanIndexes method.
