we recently migrated to search head clustered configuration. I'm trying to find how the search head manages scheduled searches and alerts. Specifically, where is the savedsearches.conf file located and how do we allow others to create new saved searches and update those saved searches? How does the search head then manage the scheduling of the scheduled searches and alerts? Do we need to configure authentication file on all 3 search heads in clustered environment ? if so, don't they send duplicate alerts/email notifications ?
