@epsilonadmin custom block.
Here is info how to create block - https://www.advancedcustomfields.com/blog/acf-5-8-introducing-acf-blocks-for-gutenberg/
So we register new block, assigned fields for this block.
We add block on page. When I try to search phrase from one of these field - page not added to search result

Hi @ilocimwca

It's simple to do with this addon
https://fulltextsearch.org/wpfts-addon-files-only-1.0.1.zip

It contains some code to limit post_type to 'attachment' only:

add_action('pre_get_posts', function(&$wpq) { if ($wpq->is_search && $wpq->is_main_query()) { $wpq->set('post_type', array('attachment')); $wpq->set('post_status', array('inherit')); } });

Pretty simple. If you want to set up your own post_types, just modify this code. You can read about full WP_Query() parameters at the Wordpress official documentation.
