I've seen a lot of complaints about the fact that cohost isn't imminently searchable like most sites, and I really agree that this is on purpose because having posts become somewhat liminal and temporary is best for like,,, so many reasons
but also, just an fyi, if you add site:cohost.org to the start of a google search it lets you, well, search cohost. it's,, not perfect because google kinda sucks but yeah there ya go give that a try next time you're digging for an old post
