On reddit it’s labeled “other discussions” and it’s an auto created tab. Do you have to do a lot of curation Of the Algolia results? If not, maybe you can make it automatic?
There's a lot of curation, alas. But it's on my list to write some software to alleviate the grunty bits.
Beyond that, the way to make this a real feature would be to allow community members to craft the list of related links together. That's on the list too. And it could probably include related URLs that aren't just to past HN discussions.
