Differences between Search and Search again:

•If no listing is displayed, or the listing was created by browsing

The Search command displays an empty search dialog box. The Search Again command do not do anything.

•If a listing is displayed, and it has been created by a search dialog box

The Search command displays an empty search dialog box. The Search Again command displays the search dialog box, initialized with the actual search criteria.
