Now it's very difficult to search for an exact match. Seems like the inverted index is not used at all, and instead just encyclopedia like results are returned. Which is fine sometimes, but not when I'm looking for a phone or an function name. I would think that a neural ranking should return also the quality of the results and change to the old algorithm if it is worse than expected. But no.

At least academic Google still seems to use the old ranking function by now.
