Describe the feature you'd like

In the search results when searching for communities, the community name is shown, the instance, and the number of users. It would be excellent if it also showed the number of posts.

It would be fine if that was an approximate number. It could also be useful to show the number of posts in the last week.

This isn't available in the back end, and unfortunately it'd be a significant performance cost for postgres, so we probably won't add it.

This is available in community aggregates already, which is even part of the API response. It just needs to be displayed in Lemmy-UI. Another useful metric to display might be MAU.

[dessalines]

Oh, for some reason I thought they were asking about the total number of search results, IE a paging thing.

@Nothing4You oh yeah, MAU would be super useful. Both together would be a really good indication of how alive a community is
