I'd love to agree that comically amateurish, but apparently there's something about settings dialogs that make them incredibly difficult to search. It takes Android several seconds to search its settings, and the Microsoft start menu is also comically slow if you try to access control panels through it, although it's just comically slow at search in general. Even Brave here visibly chokes for like 200ms if I search in its preferences dialog... which compared to Android or Windows is instant but still strikes me as a bit to the slow side considering the small space of things being searched. Although it looks like it may be more related to layout than actual searching.
Still. I dunno why but a lot of settings searches are mind-bogglingly slow.
(The only thing I can guess at is that the search is done by essentially fully instantiating the widgets for all screens and doing a full layout pass and extracting the text from them and frankly that's still not really accounting for enough time for these things. Maybe the Android search is blocked until the Storage tab is done crawling over the storage to generate the graphs that are not even going to be rendered? That's about what it would take to match the slowdown I see... but then the Storage tab happily renders almost instantly before that crawl is done and updates later... I dunno.)
