To see it in action:
Crust.piefed.social (the Piefed development instance)
Not all instances implement it yet, I guess it depends how often they pull from the dev branch
Example of search for 'movies'
you brought up top month and I don’t see how you’d want that to work
The truth is I don't want "top month". What I really want is "best result, filtered by this month". But unfortunately that doesn't exist, and in the absence of that, I use "top month".
