Ah, right. Well you can't do that!
When you search, companysearch.php gives you the results based on what you typed in on of the text boxes on
search.php, the search page. So going straight to the companysearch.php page will reveal nothing because you haven't given it anything to search for.
Have a look at
this thread, where it is suggested that the 0870 number could be included in the URL. This would do what you want, but, as DaveM says, it would be open to abuse.
If you want to save some results, it works when saving pages as I described above.
