Amen. App-store search is an offense sham, wasting users' time and stealing from developers. And +1 to pitiful Mail search. But Apple has long suffered from a peculiar learning disability in regard to search. Not only does Finder fail to find files matching search strings that it's showing you IN THE CURRENT DIRECTORY... but both Finder and Spotlight provide no option to include WHERE it found stuff in search results…
Finder has always been the weakest part of Mac OS for some reason. The one UI that Windows beat them on.
Microsoft has degraded Explorer, though. For example, you used to be able tell which directories were empty by simply noting whether there was a + symbol next to them. Clever and time-saving.
Now, not only did MS replace the universally-understood + sign with a stupid triangle, but it now HIDES all the triangles unless you happen to roll the cursor into the left pane. WTF, WHY?
Oh, and if you select multiple files in Explorer and right-click to say "Open with..." NOPE! Microsoft inexplicably removes "open with" if you select multiple files, even files of identical type (PNGs, for example).
The opening of multiple files was fully functional 30 years ago. WTF?
