The What's Up Tonight tool is presenting a very large list of matching objects that return Object Not Found. This highly diminishes the usefulness of the tool. Meanwhile there is no issue finding these objects in the Find Tool and the What's Interesting tool. So there appears to be a database issue to resolve.
