The search window is opened after the File Filter Criteria have been
specified. This powerful feature allows you to filter the display of an
entire FTP site. The file list pane is augmented with two buttons that
allow you to change the File Filter Criteria and to initiate a new search as
required. The search is applied to the active directory in the Address Book
pane. You can search the entire directory tree below the current path by
checking Include Sub-Directories as part of the filter criteria.
