Wordpress admin search is not working for any type posts i.e posts,pages,comments or any other custom posts.
Whenever trying to search for say string without quotes "my new post"** it always returns.
Search results for ""
No matter what the search string is.
Also all of this error is on the pages related with edit.php
you can try writing something that appends to your query var when the search is initiated something as such as:
function gt_search_filter($query) {
global $wp_query;
if ($query->is_search)
if($_REQUEST['s']){
$wp_query->query_vars['s'] = $_REQUEST['s'];
}
return $query;
}
add_filter('pre_get_posts','gt_search_filter');
this worked for me but remember this is quite insecure and not advised what other thing you can do is adding more layers of filterations and everything before you finally give it to the query string.
