Save as a user news
From OpenKM Documentation
User news is a push service that each 30 minutes OpenKM fires users queries looking for some user information news. Results will appear on dashboard new panel, and only contents new results that has been appeared since last time query has been executed.
To enable a query as a user news, simply mark the check box option “Save as user news” before saving query. You can execute user news query like as a normal saved query .
