I did not know this is how you handled it
Not really up to me. This is how Hive node, Hivemind and HafSQL handle it. I use the whole Hive decentralized stack and without proper metadata those systems simply don't index the post/comment for the tag.
I've been doing it the brute way... parsing through snaps, looking for the tag. ha!
i guess at least im not breaking the "single source of truth" rule. But I basically built a recursive function. It loads results client side and displays.
your way is waaaay better.
