For example: I tried to search all 3 communities from sopuli.xyz featured in this comment https://kbin.social/m/lemmy@lemmy.ml/t/2938/Which-subreddits-would-you-most-like-to-see-on-Lemmy/comment/6790/
search for y2kaesthetics did not work
for frutigeraero returned only my comment linked above
only for weirdcore succeeded
Ok, in https://kbin.social/m/kbinMeta/t/8373/Lemmy-compatibility someone figured out that you need to replace the ! with a @ and then it works to find it through the search. I tried it and could subscribe to the magazine I wanted.
Do you search in the search bar or in magazines?
