Does this currently work with the core version of user field search? I took a look at the commit for that release and it looks like it should. I don’t have a handy instance now to test it - but curious specifically what you feel is missing!
I ask because I had made a plugin for this use case in 2020, but never got around to open-sourcing it. I’m really interested in exploring use cases for making content searchable in communities (especially across multiple platforms - so if this happens to be your use case let me know, would love to chat further!).
Anyways- here’s the plugin, i’m like 80% sure it’s redundant with how the core version ended up getting implemented, but in case there are improvements or collaborations in development- I thought I’d share.
