This will display the frequency of the hosts for the results. The host is taken to mean the first part of the URL for a webpage, excluding 'www' if present. For example, for the URL
http://www.guardian.co.uk/sport/2009/jun/24/formula-one-fota-breakaway-talks
the section shown in bold (guardian.co.uk) is the host.
You can access this by selecting the 'Hosts' option in the 'Summary of Results' group in the 'Select a task..' drop down menu on the results screen.
A table will be displayed containing a breakdown of the hosts in frequency order.
