Search for a community requires ! in front. Is that really necessary?

On Lemmy.ml, I click Communities then in the search box I type "uganda@baraza.africa" and click the Search button. The response is "No results.".

But then if I type the "!" prefix, i.e., "!uganda@baraza.africa" and click Search, the community is found.

This seems to be a UX issue. Not everyone will know the community needs the "!" prefix.
