[GeoNetwork-users] How to force or control "Recent Changes" and GeoRSS feed updates?

How do I control or force updates to GeoNetwork 2.4.2's "Recent Changes" and GeoRSS updates?
Does "recent" refer to the latest new metadata record additions (loading) or to metadata with the most recent metadata date stamp (creation)?
Ciao, Wolfgang
