• Yes, with a major caveat. An instance will search only communities that at least one user on the instance is subscribed to and only as far back as the time the first user on the instance subscribed to the community.

    • Lemmynet’s design structure has some weird choices in it, motivated either by laziness or to keep garage servers from being overwhelmed, and that’s the biggest and weirdest one. I’d like to see federation = full and complete synchonization from server launch to present, but I doubt the motivation is there to implement it. Maybe things will be different when kbin eventually surpasses Lemmy

      • If that was mandatory you’d kill of smaller/personal servers, which is bad.

        Should be a host option to decide what to sync.

        Oh and you’d also need to solve an issue with a new instance joining and completely flooding everyone else with requests for past content.

        It’s all solvable but the reasons to do it this way aren’t just random.

        Oh and you also face issue with duplicate content (between instances) which search engines generally don’t like.

        Ideally there would be native integration for search engines where they’d just connect with the fediverse like another instance and have special handling for the content. They could either display the content in their own UI or allow the user to pick their default instance that’d open the given content

        I suspect that’d be the best way but we won’t see it unless federated apps become mainstream.

  • I’d say the short answer is no and the long answer is yes.

    Searching across instances is difficult, for the reason RandomBit mentioned in this thread. But you don’t go to reddit and expect your search results to include Hacker News, Twitter, etc. When you search on reddit, it also only searches the local instance, it just is that there is only one instance. So the search is exactly the same as reddit.

    With that said, there is probably room for a service that provides cross-instance search by subscribing and indexing communities like a crawler, rather than relying on users to create the federation.

    • FediSearch I guess is similar to your idea, though I think the goal would be to make a new and open search index specifically containing fediverse websites instead of just using Google. I also feel like the formatting should be more like Lemmy, with the particular post title and short description showing instead of the generic search UI.

      The idea of a fediverse search is really cool though. If things like news and academic papers ever got their own fediverse-connected service, I could see a FediSearch being a great alternative to the AI sludge of Google.

      • That would be the question. You can certainly do a site search. At least duckduckgo can do that. It may not be so easy to just search lemmy, the threadiverse, or the fediverse for example. Do not know.

        • All search engines do this. You can append or prepend site:<domain name>.<tld> and it will filter by site.

          They even do wildcards, so to search any lemmy instance with “lemmy” in the domain name, you could do site:lemmy.*

          To include others, you can us an OR operator.

          So to include kbin.social you could use the following filter: site:lemmy.* OR site:kbin.social

          Unfortunately, this won’t work for instances that don’t have lemmy in the name.

      • Probably if the instances have lemmy in their domains like mine, or lemmy.ml, lemmy.ca, or in their name (mine is “pe1uca’s lemmy” so if the domain was different maybe search engines could also work with that), but not for ones like, lemmit.online, sh.itjust.works which don’t have lemmy neither in their names nor domain.
        It’d be like searching for content posted in sites which use wordpress.

      • I don’t know if you need to pick a different one per se. It’s all likely a work in progress. I did notice the community subscribe buttons are also often screwed up and are plain text instead of a clickable button. Not sure what that’s all about. I’ve just been enjoying version 0.18 and the owner has the extra filters for top of the last 12, 6, and 1 hour
