I will not add more commits in this. Just added fix for search. Noticed that anime Dungeon no naka hito is categorized as music

Hey, I noticed some weird behaviour when it comes to searching.
If you try to search for the anime Darling in the Franxx, it only returns the Special, not the main anime. On the site however, it shows both.
I tried using the different filter Types, and apparently, the main anime isn't categorized as anything. It doesn't show up on any "Type" filter. Only the Special shows up on "Special". Wow.
It's completely fine if you don't want to bother with this, just wanted to point it out.

Ok I'll fix this. Anix categorization too messed up IMO.

@riimuru I added new commit to address this:
