How can I subscribe to new communities with raccoon? I tried the explore feature with the filter set to all, but no communities are found.
I tried multiple times to give my server the chance to fetch the remote community.
I searched using the full address with a leading !: !raccoonforlemmy@lemmy.world
The "Explore" section with "All" filter is the right place, you can use the "Community" tab to narrow down results. However, all this screen does under the hood is a GET /search with the q parameter (for the query) and this is far from optimal, moreover it does not work passing a community handle. I'll look into it for this week's release, thanks for the hint...
I discovered, by tracking the calls made by the web UI, that there is another call they make (and then results are combined), the GET resolve_object. It's an easy fix, definitely I'll do it!
There also is the "Users" option. They correspond to the available search types in the Lemmy APIs which are: All, Comments, Posts, Communities, Users and Urls. The last one was added at a later stage and I have no idea what it does...
In any case it would be theoretically possible to filter posts on another instance, I'll have to experiment a little bit... basically I would present the same Explore screen but you access local posts on the other instance in guest mode.
