When you`re dealing with MOSS in public site scenario and using search – you probably don`t want internet users of your site to see content author in search results. As you know you will get all of the subsites and some lists and last thing you want to show is that [contoso]\administrator is the admin account name who created the content – it`s a security risk let alone looks irrelevant to a user.
So how do you hide this all from users without major changes – well, you need to change XSL of the Search Core Results webpart on your search page, and find <author> search property that will look like this:
Remove the property from the list and save your webpart properties, publish page and you`re ready to filter your search results.
