ApacheSolr Search error - This webpage has a redirect loop (Chromium) OR The page isn't redirecting properly (Firefox)

Hi,

I think that should not be a valid version. That it worked for a particular case does not imply it works for everybody. ;)

So I re-open it and re-direct to ApacheSolr Search issues because that is a problem of ApacheSolr Search, not of Display Suite or whatever module.

By the way, I have the same problem. It begin just yesterday and it looks it has too many indexed nodes or they messed up in the index.

Thank you.

I'm not seeing a clearly defined problem statement here. Please explain how we can reproduce?

We have installed Apache Solr Search Integration engine to search through Profile types.

Everything just worked fine until we begin to adapt the page to Multilingual adding Spanish and French language besides English. Since that, the search/results just gets to a 'This webpage has a redirect loop (Chromium)' and 'The page isn't redirecting properly (Firefox)'.

I tried to figure out more detailed error but neither the recent logs nor Apache solr Statistics show any.

Hope this can helps. I will move this issue to Major priority because any Social Network, Website based on profiles, etc. Is just nothing useful if the search engine does not work at all.

Not major until proven that apache solr is the problem.

Please explain in great depth how someone else can reproduce this issue. I have never seen this happen before, so it could very well be a problem of a different contrib module or a combination of some?

Hi Nick_vh,

I'm the project manager in the project RaulMuroc was talking about. First a description about how it happened: Everything was working just fine, we had multilanguage active with two languages (french and spanish) and we kept the language switcher hidden until we had time to finish the translation. We started translating nodes, blocks, ubercart products, etc. and at some point solr started failing with the described error (Error 310 (net::ERR_TOO_MANY_REDIRECTS). In that time we didn't change any module nor installed new modules. The only changes were creation of new profiles by users and the translation.

Some date about our installation, please tell me if you need any extra information:

I just noticed two things Nick,

- We met in Drupalcamp Barcelona 2010 (we did a couple of projects with Ateneatech). So nice to see/read you again.

- The second is that I forgot to describe the project (shame on me). Our site is a social network. Users create profiles (profile 2 module) and the main purpose of the solr is to index the profile2 profiles and their addresses (location module).

Hi there again! :)

I noticed that you forgot to mention the exact version of the Profile2
Also I can see you are using

"Solr search
7.x-1.0-rc1 Offers an implementation of the Search API that uses an Apache Solr server for indexing content.
Requires: Search API (enabled), Entity API (enabled)"

You should never use both modules on the same site unless you have an explicit reason for it? Could you try and see if disabling that helps? I can also not see which version of apachesolr you are using? (and if it is -dev, update to the latest one)

Hello,

We deactivated Solr Search and Search API (both not used, it is Apachesolr directly used). Flushed caches, re-indexed, cron, updated Apache solr search integration module to the latest stable release... And still gives the same error.

From my point of view: It is looking everything began when the site was made to be multilingual but cannot confirm that :S

More information:

We were indexing a Location Field inside Profile2 type nodes on Multilingual site. So it is needed:

Apachesolr Search integration + ApacheSolr Multilingual + Apachesolr Profile2 + Apachesolr Location

Perhaps some of these modules just has broken down? (Note: ApacheSolr Location is still under dev).

More info, nick

Profile2 is 7.x-1.3

and solr is:

Solr Specification Version: 1.4.0
Solr Implementation Version: 1.4.0 833479 - grantingersoll - 2009-11-06 12:33:40
Lucene Specification Version: 2.9.1
Lucene Implementation Version: 2.9.1 832363 - 2009-11-03 04:37:25

Was this resolved already somehow? Looks like a very specific error that is not easily reproduced?

I just recovered a very old backup. It works and that's it. Hope is not again this loop problem.

I am almost sure this happens when: Apachesolr + APC (Alternative Pages Cache). Somehow Apachesolr indexes non-existing nodes which they are in cache and so on makes an infinite loop.

I discovered this because when recovered backup, it broke again with same error. Then I recovered again backup but without APC (I was thinking there should be problem) and now it works perfectly :)

Thank you!

The solution exposed above:

I disabled all search types except apache solr and saved. Then I enabled all the other search types again and now 'search display' works again.

Nicely works!

I have the same redirect issue. So far all I can pinpoint it to is that I disabled all of the other search types. I however, do not want the other types enabled. Is there a way to resolve this without enabling other search types?

Oh, forgot to mention that this only happens when I go to the solr search path search/site. So no search criteria yet. That leads to the loop.

I'm also using the 7.x-1.0-rc4 version of the apache solr module.

Appears that the issue is panels related. When I disable all the non-solr search types a redirect loop happens when I try to enable a panel for search/site. If I disable the panel then the url works as is should and no redirect happens. Only, no panels. :/ Weird. Anyway, ignore my comments in this issue as I don't believe its solr's fault.

Let me guess, you were trying to apply panels on page like search/blabla using Page Manger?

#17 - I have the same issue. All is well unless I try to load search/site directly with no keyword; I get the redirect loop if I do. No panels, no page manager for the search page, it's the default 'in code' page from ApacheSOLR.

@webby7097 That is because of drupal search module. Look at search_view funtion, if you will comment drupal_goto there - it will fix it.

x610, I tested your suggestion in my sandbox and it does indeed fix it; however, it requires hacking a core module. Can anyone suggest how to implement this fix without hacking the core search?

webby7097, I assume you can just disable core search, no?

Unfortunately, no; the core search module is required by Apache Solr.

In my case I fixed this by editing the Apache Solr version of the core search page (/admin/config/search/apachesolr/search-pages/core_search/edit) to change its path from "search/site" to "search/basic" (thereby getting it out of the way), then used Page Manager to build a new version at search/site and used that.

I get the feeling different people are experiencing this bug in different ways, though.

AS best I can tell, this is still an issue. Is it because drupal core search calls a seach_view function that looks for all modules that hooks search and in the case of apache_solr, hits this function below:

function apachesolr_search_search_info() {
  // Load our core search page
  // This core search page is assumed to always be there. It cannot be deleted.
  $search_page = apachesolr_search_page_load<em>('core_search');</em>

  // This can happen during install, or if the DB was manually changed.
  if (empty($search_page)) {
    $search_page = array();
    $search_page['page_title'] = 'Site';
    $search_page['search_path'] = 'search/site';
  }

  return array(
    'title' => $search_page['page_title'],
    'path' => str_replace('search/', '', $search_page['search_path']),
    'conditions_callback' => variable_get('apachesolr_search_conditions_callback', 'apachesolr_search_conditions'),
  );
}

Which always returns attributes for core_search and its corresponding panel, regardless of what page you have configured to be the default. So you get search/site runs hooks on search, which always returns search/site as the override.

So, my question is, rather than always pass in core_search, should it look to see what page is configured as the default and use its machine id instead? Otherwise, you traverse into another function

function apachesolr_search_page_load($page_id) {
  $search_pages = apachesolr_search_load_all_search_pages();
  if (!empty($search_pages[$page_id])) {
    return $search_pages[$page_id];
  }
  return FALSE;
}

But even though it loads all pages, it will only deal with the ones passed in (core_search). Where is the default configured page handled?

This is definitely an active issue - though it may be a Chaos Tools issue rather than one for this module (?)

To reproduce this error on a brand new site:

1. Enable Page Mananger, Panels and Apache Solr Search
2. Set up apache search
3. On search settings page disable other search modules (node and user)
4. In Page Manager enable the /search/site/!keywords page, edit and create variant
5. Try to visit my.domain/site/search

This resulted in a redirect loop and caused the following error:

Notice: Undefined index: core_search in page_manager_search_build_subtask() (line 216 of /var/www/drupal-7.34-test/sites/all/modules/ctools/page_manager/plugins/tasks/search.inc).

The use-case here is any attempt to have Panels render the Apache search page when Apache is the only active search module. In fact, this happens even when the other search modules are active. I do not think this is a particularly narrow use-case.

#25 is a reasonable work-around though it leaves the secondary search page active (in that comment the example given of "search/basic")... unless you want to use facets, because the facet panels provided by the facet API redirect the user to the apache search page.

EDIT: The workaround probably works with facets if you set your secondary search page to 'default'. I haven't tried it.

Ok, I have tracked this down to this module, not Chaos Tools, because apachesolr_search is only changing the page argument for /search/site/%menu_tail and not /search/site when it creates a path.

The "core_search" argument gets passed to Page Manager when a user tries to access /search/site and because it is disabled Page Manager gets caught in a loop.

I'll come back to this tomorrow and see if I can figure out how to make apachesolr_search affect the path that contains no keywords, and whether that is a good idea, or not.

Found a few things:

• apachesolr expects the page argument of a search page to be the machine id of the specific search page
• ctools search plugin expects the page argument to be the module name
• apachesolr does not override $path/%menu_tail which, funnily enough, tricks Page Manager into allowing users to override the included 'core_search' path (but not others).
• instead it uses $path/% which page manager knows nothing about and doesn't try to override

I tried changing a few things at the apachesolr end and everything broke.

I was successful in making some very minor changes to the ctools search plugin that break the 'node' search but otherwise seems to work for this use-case.

WARNING: This patch breaks normal Drupal core search.

NOTE: This patch is for Chaos Tools, not Apache Solr. I am sharing it as a work-around for those that wish to use Apache Solr Search as the ONLY search type and render the page using Page Manager.

I think the next step will be to try and create a working plugin for Chaos Tools within this module to avoid breaking core search.

#29 worked for me.

Although I enabled my page in the page manager, the default results page was rendered. So my enabled Site page was never reached.
Only if I went to /search/site in stead of /search/site/!keyword, I got the redirect loop error (firefox, chrome, safari).

As I see it, the work (and research) of Darvanen really adds up with my problem. I've been looking into the code and everytime I got to the search.inc file (around line 216), but I am using the stable 7.x-1.7 version.

Thank you @Darvanen for the patch in #29. I'd love to work on this more since I now have several sites suffering from it. Have you posed this over in the ctools queue, bychance?

Also a note to others suffering from the problem, the patch above does not make the page manager handler for Apache Solr work, it does just the opposite. It stops page manager from trying to take over the Apache Solr search page like it does for all the other search pages. If you actually want Apache Solr to work with panels, you'll need to choose a different URL for your search pages. (See the README in the Apache Solr Panels module for more info on that)

Hi Jen,

I have not done so as it breaks normal core search to fix a problem with a specific use-case (solr). I think it would need a lot more work to undo the discrepancies between ctools and core when it comes to handling the menu-tail.
There may even be significant reasons they chose to go down that path, I'm not sure.

I would certainly welcome the change though. I am no longer in charge of any sites using solr so I may not be able to assist as much with testing as I would like, happy to help however I can though, best of luck!

--I was able to use panels to render my solr search page (and the facets) using this patch, perhaps it is not complete?

Two years on...and I am still observing this behavior. Not sure if any fixes to this issue have been stitched into this module or ctools or what, but here's how I fixed it without patching anything...

1. Enable the pm_existing_pages module.
2. Disable the search/site/!keywords page supplied by this module in page manager.
3. Create an existing page (see pm_existing_pages module), set the page path to "search/site/%". Create a variant of type Panel and put the existing page content into a pane. You can also add facets to another pane if you wish.
4. Create another existing page, set the page path to "search/site". Create variant of type Panel and put the first existing page created in the previous step as the content of a pane. Add facets if you wish.
5. Save and clear cache.
