Forum search feature and language filter in follow list

[Picks]

Hi, I'm on mobile at the moment and can't find a search feature in the forums for the life of me. Is there one available somewhere?
Also, is there a way to filter your 'follows' chapters to a specific language? My follow list is becoming flooded with chapters being updated/uploaded in languages that aren't relevant to me (this is what I was going to use the forum search feature to find out).
I've set my language preference on all the settings I can find, but still seeing every language in my list.
Thanks in advance for any help given.

Edit; found the language thing. I'm a dummy.
