For the sake of argument, let's assume there are some things Windows does well. Search is not, and never has been, one of them. I think after 30+ years it's time give up. There are tools like Agent Ransack that do search on Windows right. You can search by file name and/or contents. Search by date, file size, extension. Search with regex, wild cards, or literal strings. No fudging results like it's being paid on commission--searching for "tests" does not return results for "test"--and no fancy guessing on what you meant--search for "mime" does not return results for "meme".
That other groups have accomplished this with much less resources than Microsoft has, might just mean MS doesn't have what it takes for this particular task.
