Page not found on some search pages on my search result

On the page two of the sophie query, what parameters the relevanssi_do_query() gets and does it return any posts?

What’s in the $wp_query->query_vars on the broken page load?

How are the actualites fetched?

Thank you for your response Mikko.

The thing is that the code bypasses the search.php file on page 2 and gets straight to 404 response. relevanssi_do_query() is not called on that page then.

$wp_query->query_vars is worth the following on the 404 page:

=> 0 [monthnum] => 0 [year] => 0 [w] => 0 [category_name] => [tag] => [cat] => [tag_id] => [author] => [author_name] => [feed] => [tb] => [meta_key] => [meta_value] => [preview] => [sentence] => [title] => [fields] => [menu_order] => [embed] => [category__in] => Array ( ) [category__not_in] => Array ( ) [category__and] => Array ( ) [post__in] => Array ( ) [post__not_in] => Array ( ) [post_name__in] => Array ( ) [tag__in] => Array ( ) [tag__not_in] => Array ( ) [tag__and] => Array ( ) [tag_slug__in] => Array ( ) [tag_slug__and] => Array ( ) [post_parent__in] => Array ( ) [post_parent__not_in] => Array ( ) [author__in] => Array ( ) [author__not_in] => Array ( ) [ignore_sticky_posts] => [suppress_filters] => [cache_results] => 1 [update_post_term_cache] => 1 [lazy_load_term_meta] => 1 [update_post_meta_cache] => 1 [post_type] => any [posts_per_page] => 9 [nopaging] => [comments_per_page] => 50 [no_found_rows] => [search_terms_count] => 1 [search_terms] => Array ( [0] => sophie ) [search_orderby_title] => Array ( [0] => gretacdma_posts.post_title LIKE '{889f9dde2793b886b91eb47378897f22eb2098e471145dec5d64e49020558861}sophie{889f9dde2793b886b91eb47378897f22eb2098e471145dec5d64e49020558861}' ) [order] => DESC [operator] => OR ) 

On search.php, after displaying the formations, actualites are fetched this way:

      $pq         = new WP_Query('s='.$search_txt);// Posts Query                                        
      $pq->query_vars['post_type']        = 'post';                                                      
      $pq->query_vars['posts_per_page']   = 9999;                                                        
      $pq->query_vars['orderby']          = 'date';                                                      
      relevanssi_do_query($pq);

If easier, I can give you access to the code repo with your email address.

I think part of the problem is the fact you’re doing the query on the search results template. If the default query doesn’t find any results, as you can see the search doesn’t even go to the search results template.

So, instead of doing the query on the search results template, you should do it before the template by adjusting the parameters for the default query. Use pre_get_posts or relevanssi_modify_wp_query to change the default query to change the post type and other parameters and use that default query (and then fetch the news with another query).

This way the default query will match what you display on the page, and the paging will work.

I understand better now. I was kind of doing it like that (via pre_get_post) but was facing that pagination issue, and searching for an answer I found a post of you saying having a query_posts in the pre_get_posts hook would screw things up, so I back pedaled from there and moved everything in search.php. I might have gotten it wrong though.

I try your suggestion out and reach back. Thanks for your help!

Hmmm…

This is how I implement relevanssi_modify_wp_query in function.php

function modify_search($wp_query) {
  $wp_query->set('s', get_query_var('s'));// fetch search string
  $wp_query->set('post_type', 'formations');
  $wp_query->set('posts_per_page', 9);
  $wp_query->set('paged', $wp_query->query_vars['paged']);// paging

  // filtrer suivant la bonne taxonomy
  if (isset($_GET['taxonomy'])) {
    switch ($_GET['taxonomy']) {
      case 'formation-diplomantes-cpf':
        $ta = ['formation-diplomante', 'formation-eligible-au-cpf'];
        $op = 'AND';
      break;

      case 'toute-formation':
      break;

      default:
        $ta = $_GET['taxonomy'];
        $op = 'IN';
    }

    if (isset($ta)) {
      $tq = [[
        'taxonomy' => 'type_form',
        'field'    => 'slug',
        'terms'    => $ta,
        'operator' => $op,
      ]];// Tax Query

      $wp_query->set('tax_query', $tq);
    }
  }

  return $wp_query;
}
add_filter('relevanssi_modify_wp_query', 'modify_search');

I get no result: https://cdma.happy-dev.fr/?s=design&taxonomy=toute-formation

Even though $wp_query->query_vars seem correct to me. I’m echoing them from search.php:

global $wp_query;
print_r($wp_query->query_vars);

Output:

Arf… The polylang plugin was actually the cause… Deactivating it solved the problem.

Many thanks for your helped. Without your help, I would still be on it. Thanks!
