Hi all!

I'm proud to present this patch, http://drupal.org/node/77514.

It does some simple but yet very useful changes to the error reporting system. Basicly this is a version of Search404 (http://drupal.org/node/26010) on steroids, with some enchantments. All features from Search 404 are kept. It has been rewritten to be more stable, secure and fast than before. New features has been added:

• The error message is now configurable
• Three special paths has been added;
• <blank> - It's the classic Drupal 404 page, just an error message
• <front> - Invokes the frontpage - with an error message set to $message
• <search> - This is what Search 404 accomplishes and is also the standard 404 page if nothing else is specified. It performs a search on the words from the requested URL. The options to configure Search 404 remains:
• Display a link instead of the search results directly. This feature is particular useful when many bots is hitting the site.
• Jump directly to the search result when there is only one result.
• Use OR between keywords when searching.
• A list of words that should be ignored (php, html etc)
• Of course any Drupal path can still be specified
• There's now an option to send "404 Not found" header or not
• Brand new 403-handling:
• Can use <blank> and <front>, but also <login> which will display a login form.
• Configurable error message and option to send "403 Access denied" header

Care has been taken to not create loops, such as the user don't have access to the 404 page, and the 403 page itself isn't found.

One reason why this should be in core, is that error-handling surely is someting the CMS itself should take care of.

How to test:
1a) Visit: http://forngren.com/fantastic40x/
1b) Make a fresh Drupal HEAD install, and make sure that everything seems ok. Apply the patch attched
2) Fool around with the site
3) Report results back in this issue

I can't believe how many sites miss this trick. I was looking for a radio programme 'Loose Ends' on the BBC website. I tried www.bbc.co.uk/radio/looseends and got a 404.

Why? How difficult would it be to put the non-matching part of the URL into a search and bring up 'Sorry, we couldn't find an exact match - did you mean...' then list trip_search results or something.

If anyone can figure this out, it should go into core Drupal functionality.

A good CMS has an excellent search facility.

A good site has this search facility on every page.

When I'm looking for something on a site, as soon as it renders I instantly judge it. If I can't quickly see a search box - I hate it. If there is a ton of content on the front page - I'm not a fan. If the search is slow, or doesn't yield coherent results - I'm dissapointed. If it's Flash - I'm not impressed.

Sideeffect
There is a tiny sideeffect, though. After using this for a few days on a test site with 6 nodes, I stopped using the navigation and just typed what I was looking for in the URL. I think that Bert Boerland can confirm this.

Final words, contact info and more
First of all, none of this would be possible if it wasn't for the work done by Lars Sehested Geisler/larssg, the maintainer of Search 404, and Bert Boerland, which has been a great support during the process of writing, testing and documenting this patch. Since I've summerholidays I can usually fix bugs/errors within a few hours (awake between 10-24 GTM +2). If you want to discuss this patch, please, do so. I'm in #drupal when I'm awake. You can also use my contact form (http://drupal.org/user/40238/contact) or skype me (forngren).

Cheers!
