Figure 1 - The Searching and Indexing History Cleanup overlay
The ...history cleanup task removes old entries in the ConfirmitSearch database. The Days to expire... value specifies the number of days the history is to be kept for each task before it is deleted.
The task parameters specify how long internal activity tracking data is kept. This data is really used for extended troubleshooting, so unless you are in the process of troubleshooting something related to the Forsta Searching service, the default values can be used when scheduling this task.
