Search custom fields

Or is BS plugin compatible with https://www.ads-software.com/plugins/wp-extended-search/ ?
I also found this info: https://adambalee.com/search-wordpress-by-custom-fields-without-a-plugin/ Would that work with the BS plugin?

Thanks!

The plugin doesn’t search the meta fields but I believe your second link could work.

Additionally what I posted in the GIST (first link of your original post above) is an example to search the post meta for the relevant search results.
