It still works for me as it ever did.  Maybe you didn't define a
search that runs for long enough?

There should be a count of matches displayed in brackets on the mode
line; with a long enough search, like using "grep -R" on a large
directory tree, I see the numbers increasing, and I can go the *grep*
buffer and see the stuff coming in.
