Search not working when in "page missing" page

Drupal in general has a bug where search wasn't working on 404 pages. Maybe we missed a fix that went into core?

Same problem here.

[Edit: See #292565: Regression: Can't set /user to 403 page (was: login destination is broken)]

After a little more investigation:

When I visit example.com/sifjsdof (some garbled text that returns 'Page not found'), I get the form appropriately...

<div id="search-box">
  <form action="/sifjsdof"  accept-charset="UTF-8" method="post" id="search-theme-form">
  ...

The action is set to the current page.

However, I'm guessing that ApacheSolr is not fired when a request is sent to the 404 page, so this is basically an infinite loop of 404 errors, every time you submit the search form. Not very kind to end users!

It seems (according to the linked issue above this post) that this has to do with the redirect functionality built into Drupal... but it could be something in ApacheSolr Search Integration, I guess... I haven't had a lot of time to troubleshoot.

...this seems to be a rather critical issue—the page on which people would be most likely to perform a search doesn't allow search! I noticed Drupal.org is working fine on 404 pages - do they have a customized Solr implementation?

I think this is a core issue with the search module: http://drupal.org/node/292565#comment-1065064

But it seems like that issue was fixed already (see http://drupal.org/node/292565#comment-2039636), and even though I'm running 6.15, the form is not working... seems like it has to do with apachesolr, no?

Hmm, good question - guess I should have checked the status. apachesolr is using the core search framework, so i'd expect it to work the same, but maybe I grabbed bad code for the search block some place.

I'm using Faceted Search (http://drupal.org/project/faceted_search) and have the same problem... The core patch is present (checked the files manually) so it did get into the Drupal core properly, so these other modules must be the culprit imho...

EDIT1: turning off faceted search did not 'fix' the issue... Is the patch properly working then? Looking into it...
EDIT2: when using the search block, the patch works fine, when using print $search_box it does not...

I fixed it, moved to: http://drupal.org/node/730322

Core issue (for tracking purposes): #730322: Search not working on 404 page when using print $search_box in template files

Confirm that #730322: Search not working on 404 page when using print $search_box in template files is the issue to follow for this.
