In Mastodon, when you search a Hashtag, How do you sort by most retoots?

I cannot figure it out. I search for anything, and it always show you the most recent comment that includes that what you are searching. That is useful for recent or ongoing events. But if I want to see the Top of the day, or most Rotoots or something like that, to see the best comments or the best explanations/summary for something, How is that done?
