Add collection_id filter to searchbar shortcode (bis)

Hi, thanks again for your plugin !

I just want to ask if you had time to look into this question we had few years ago : https://wordpress.org/support/topic/add-collection_id-filter-to-searchbar-shortcode/ ? We are still using your plugin and still have to micromanage hardcoded custom solution for it, it would mean a lot if you could include this small change in a future version.

Best!
