How can I include Advanced Custom Fields data in Search Results?

Hi GP Friends,

I am using Advanced Custom Fields. When I add the search function to the menu, the search results are not able to search the custom fields. Is there a way to add this functionality in Generate Press? I do not want to have to use a plug-in such as Relevanssi, etc..

The code I'm testing is pasted below. It's from https://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/
Is something like this what you would recommend? Or is there a better way to add searching for advanced custom fields?

Thanks.
Denise
