I feel like a complete internet n00b, but is there a way to show the feed with more than one flair active?

I tried editing the URL structure, and then following the info below from https://www.reddit.com/r/modhelp/comments/czx9so/filtering_by_flair_a_guide_for_desktop_old_and/ but it would either only output one flair selection or just show search results.

>You can add more filters by writing -flair:Classic+-+Humor+/+Meme, -flair:question etc. This also works on the re-design for desktop, however you'll have to manually sort by "top" and "last 24 hours" every time you add a new flair to the list.

Thanks!
