Being on math.SE for a month, I noticed that almost every non-trivial question is favorited by a user. Got a bit tired searching for a problem I can think of, among questions that are likely homework or a person got stuck or things on which I don't have a clue about (e.g. "Given a locally compact Hausdorf space, ...").
So the question is:
How can I view questions, favorited at least by $1$ person (hmm, or maybe $5$)?
I've already seen
infavorites:id in search, but there seems to be no option
infavorites:* available. It turns out that I can use
favorite_count>0 but I do not know how to manage with it.
