if you use this often, you can add a keyword search (firefox-based browsers) or a custom site search (chromium-based) with this URL

https://icon-sets.iconify.design/?query=%25s

(use %s after equals; some lemmy front-ends seem to be rendering it wrong)

and a shortcut e.g. icon

so everytime you enter e.g. icon person in a new tab, it'll run the search for you
