@rudj As far as I know you have to use the search system rather than entering this manually.There's already an open issue for this on the Pixelfed Github page so the developers are aware of the problem. I don't know what their plans are about this though.

@rudj You can't search for multiple hashtags in Pixelfed, sorry.Mastodon does have an advanced web interface that allows searching for multiple tags but you need a Mastodon account do access it: https://fedi.tips/how-to-activate-mastodons-tweetdeck-style-advanced-web-interface/
