How to add Wordpress taxonomy terms to search?

Question

Taxonomy

Guys, help me find a solution - it is necessary that the name and description of taxonomies get into the search results. That is, to search by the taxonomy terms themselves (fields - title, short description, custom field with an extended description), and not only by posts and pages. I tried to install the Ajax Search Pro advanced search plugin, but it didn't help either. Thanks in advance for your replies.

We'll have to dive into the wilds of the shit-coder. With WordPress, this is not so easy.
In short, you need to manually rewrite the sql query:

add_filter('posts_join', array(&$this, 'maginza_search_join' ));
    add_filter('posts_where', array(&$this,'maginza_search_where' ));
    add_filter('posts_groupby', array(&$this,'maginza_search_groupby'));

  function maginza_search_join($join) {
    global $wpdb;
    if( is_search() ) {
      
       $join .= 'LEFT JOIN '.Options::$table_meta.' ON wp_maginzameta.maginza_id=wp_posts.ID';			
    }
    return $join;
  }

  function maginza_search_where( $where )	{ 
    global $wpdb;
    if( is_search() ) {
      
      $findkeys='';			
      $where = preg_replace('/post_title LIKE \'(.*?)\'\)/', 'post_title LIKE  \'$1\') OR ( (FIND_IN_SET(wp_maginzameta.meta_key, \''.$findkeys.'\')) AND  (wp_maginzameta.meta_value LIKE \'$1\') ) ', $where );
    }
    return $where;
  }

  function maginza_search_groupby( $groupby )	{
    if( !is_search() ) {
      return $groupby;
    }
    $groupby="wp_posts.ID";
    return $groupby;
  }

To understand - first make a request in PHPMyAdmin or whatever you use to administer the database.
