我想搜索以下可搜索的档案：

Default Search:

/search/{keyword} -> search.php -> get_template_part(\'archive-default-search\');

Default Custom Archive:

/support -> archive-support.php

Mixed:

/support/search/{keyword} -> search.php -> get_template_part(\'archive-support-search\');

add_action( \'init\',  function() {
    add_rewrite_rule( \'/(.+)/search/(.+)/?$\', \'index.php?post_type=$matches[1]&s=$matches[2]\', \'top\' );
} );
