Is there an estimate how much memory does this site need to have the full index in memory?

I gotta say, I've seen at least one? other Typesense post here on HN at some point and I can't really comprehend HOW FAST this actually is, especially considering how much more bloat and slower general web has gone in the past years.

I don't really have anything to search for from the given site but I just played around with it to enjoy the speed.
