[Solved] WP Knowledgebase publications (kbe_knowledgebase) do not show in search results

[EpsilonAdmin]

There is a nice plugin that allows you to create your own knowledgebase using Wordpress.
But unfortunately, it's authors decided to disable search for all articles with its custom post_type (which is kbe_knowledgebase). As a result, WP Knowledgebase articles do not show in WPFTS search results. However, these articles are indexed well and you can see them while test the search in Sandbox.

To fix this, we have to re-enable the search for Knowledgebase posts.

Please put this small code snippet to your functions.php file in the main theme root.

add_action( 'registered_post_type', function( $post_type, $args ) 
{
    // Make sure we're only editing the post type we want
    if ( 'kbe_knowledgebase' != $post_type )
        return;

    $args->exclude_from_search = false;

    // Modify post type object
    global $wp_post_types;
    $wp_post_types[$post_type] = $args;
}, 10, 2 ); 

What does it do? Pretty simple. The flag exclude_from_search was set to true inside the WP Knowledgebase plugin and thus, these custom posts are not included to search.

This simple snippet fixes this.

Have fun!
