Agreed with spotlight, and when searching in a folder in finder it just doesn't work - it's absolutely bizarre.

Say i open a folder with 50 files and i want to filter them quickly, i go to the upper right corner of the window and click the little spotlight icon, then at first the OS default is to search your -entire- computer, a hilariously bad design choice, then when you change that and start typing for the hundredth time it takes minutes for anything to show up like spotlight has to index the folder again.

And sometimes nothing happens at all, and since apple doesn't show any feedback or what's going on you've got no idea if scrolling will be faster - so it's one of apples infamous "nothing is happening because we are doing magic" moment you meet daily.

What the hell is going on Apple?
