Error messages 3.5

You’re passing a stdClass object to relevanssi_do_query(), when it is expecting a WP_Query object. If you’re creating the query object yourself, make sure you construct it with a new WP_Query().

I am working by your hint

https://www.relevanssi.com/knowledge-base/adding-search-form-shortcode/

$url_segmente_array=getPathSegments($_SERVER['REQUEST_URI']);
$query->query_vars['s'] = implode(" ", $url_segmente_array);
$query->query_vars['posts_per_page'] = 8;
$query->query_vars['post_type'] = 'product';
$result_array=relevanssi_do_query($query);

a) Have you initialized the $query outside this bit of code? If not, then yeah, you’re going to have trouble. Start with

$query = new WP_Query();

b) Is there a reason you’re calling relevanssi_do_query(), instead of just changing the parameters with a pre_get_posts filter?

Thanks for your quick answer and help. I got to test it. But at first glance it seams to work.

I cam calling it because I am building my own short code (“search_form”) on the 404 page.
