I'm on latte.isnot.coffee and I just searched both [email protected] and https://lemmy.ml/c/jerboa and didn't get results for either. Neither has a message saying that there are no search results, but neither shows any results either.
Search by the URL https://lemmy.ml/c/jerboa, it's faster, if you search by [email protected] then you need to search again but only the community name jerboa
I can sometimes get them to populate if I do it twice or change it from Communities to All in the search filters. Other times, it just takes an extra 5-10 seconds after returning no results.
