you’re right
the other poster was most likely trying to stir up shit given we’re on a federated network (see also their other post), but I have been obsessed with the idea of a federated search engine this weekend
it’s definitely a worthwhile idea, but anything that does federated indexing will have to deal with moderation and abuse prevention first. those are hard problems in ordinary federated networks, but search engines specifically are targets of hostile SEO and spam in ways that few other systems are. those aren’t insurmountable problems though — just ones that need to be solved before federation is practical.
