Filter Websites From Results Form

The textarea in this form is used to list hosts one per line which are to be removed from any search result page in which they might appear. Lines in the textarea must be hostnames not general urls. Listing a host name like:

 http://www.cs.sjsu.edu/

would prevent any urls from this site from appearing in search results. I.e., so for example, the URL

 http://www.cs.sjsu.edu/faculty/pollett/

would be prevented from appearing in search results.
