I've started working on the UI/UX of Yarn Search

But I would agree with @quark that the fuzzy search is a bit too fuzzy when darch gives hits likes March

@darch speaking as an outsider, but having played with fuzzy search a bit, is it a feature?

Perhaps you are looking for a Qwerty keyboard distance for spellchecking where darch, sarch, rarch are closer than march?
