I don't know how communities are added. Is it automatically discovered or only when searched or viewed by users? The search should be much better now I fixed an nginx issue. When I search for Mastodon I get loads of results, including the community at lemmy.ml. But searching by community name !mastodon@lemmy.ml doesn't work. Sometimes it works when you click search a few times, sometimes not at all.
I'll discuss that with the Lemmy admin Matrix channel later, now it's time for bed..
Ok, I've been setting up a bunch of remote subs and I think I have a better idea of the behavior we're seeing here. I should note, I don't know what's SUPPOSED to be happening and I don't know what happens on other Lemmy instances. But I can now see what's happening here on
lemme.worldand it's consistent but complicated enough to be confusing.Basically, it seems like the community list at https://lemmy.world/communities is some kind of local cache and it seems to get populated whenever someone searches for a sub with the bang syntax, like
[!mastodon@lemmy.ml](/c/mastodon@lemmy.ml). So you end up with a confusing sequence of events like this:mastodon@lemmy.ml, but it's not listed.mastodonin the community searchbox, the mastodon community is not returned because it's not in this instances community list yet.[!mastodon@lemmy.ml](/c/mastodon@lemmy.ml)using the bang syntax. No results are returned.mastodon@lemmy.mlis already there. Reports everything is fine, other people must have been confused or that replication kicked in on its own (even though Janet JUST added it to the list, he didn't see the timing correlation to realize that Janet's search triggered the community being added to our list).mastodon, and it returns the community she's looking for.[!mastodon@lemmy.ml](/c/mastodon@lemmy.ml), STILL gets no results even though the community is in our community list. Edit: Since writing this I've been told that lemmy searches that return zero results may actually just not be finished. Maybe I/Janet would have gotten a result here if we waited long enough. Or maybe would have eventually gotten a result even at Time 1.)So you can see that you'll observe different behaviors based on whether you do a keyword search, bang-syntax search, or browse the community list... and you'll see different results depending on whether ANYONE has searched using the bang-syntax yet.
So the reliable way to subscribe to a community is first to search by bang-syntax, then scan the community list (or keyword search) AFTER the bang-search... and then you'll find your community.
No idea if this weird behavior is by-design, a bug in Lemmy itself, or a problem with the
lemmy.worldsetup. But I'm pretty sure it explains all the weird behaviors we've seen around communities sometimes being easy to find and other times being hard to find.Also stop searching with bangs use the https://lemmy.ml/c/mastodon format
URL searches exhibit the same behavior as bang-searches. Is it documented somewhere that the bang-syntax is deprecated? If you visit any community on lemmy.ml, the bang syntax is how it recommends to search for the community on a remote instance, like in the upper right box of https://lemmy.ml/c/lemmy.
The Lemmy project is not well documented and is not close to being settled. I'd consider it beta software
As a new user on sh.itjust.works this has been my experience as well. It also seems like just pasting the link to the community causes the search to find it as well, which can be a bit more convenient than typing out the bang. Even pasting the link to a comment from a different community procs the search to find it. It is weird that it doesn't show up the first time and you have to redo the search though.
Thank you for the research. I will take this up with the Lemmy devs.
There are 2 searchs that you could be cross talking about. The search on the Lemmy.world communities page and the search in the lemmy.world header (or hamburger menu on mobile)
Are they not the same? They both take you to https://lemmy.world/search/. At any rate, I'm visiting https://lemmy.world/communities and using the default
typeconstraint on that page to search forcommunities.They don't work the same in my observations
I think the difference is one of them auto filters to only communities and one searches for all types, that was a bit hard for me to notice at first
Yeah, that's true by default. But in both cases, the search results page includes a dropdown of
types. The header version defaults toalland the communities version defaults tocommunities. But they're the same search results page, and you can filter the types however you want on either if you change the value of that dropdown once you arrive at the initial search results.I don't have insights into how the communities get discovered, though I'm new to the ecosystem too. If I find anything as I'm reading around I'll pipe up. In the meantime I'll try other ways of searching as you've described. Get some rest, cheers.
