I made a module once which you can find at http://cvs.drupal.org/viewcvs/drupal/contributions/modules/search404/ It shows a message that the page was not found and then presents the results of a search. On 11/29/05, David K Norman <deekayen@deekayen.net> wrote:
I just wanted to make sure this wasn't implemented before I submitted an official feature request issue.
Sometimes I remove an attachment from a node, but Google still keeps it indexed for a while. I can see people still trying to access the file in my logs, but they get a 404. I think it would be cool if the 404 message was able to say "Page not found", but then use the missing URL as a search string to display other possible similar pages in the site under the Page not found message.
