Tweaking Workers::FetchPublicPosts

When diaspora searches for a user, it automatically fetches its last 15 posts (Workers::FetchPublicPosts).
Is there a way to tweak that amount?

No, and that’s only a more-or-less-working workaround (which also only works for diaspora, because it’s not part of the protocol spec) which will probably be removed at some time when we found something better (as part of the protocol) and we don’t need that hack anymore.
