Microsoft academic was imo much better. Instead of just entering words into a text field, you also had tags like biology or chemistry that you could include or exclude. Sure you can manually do that even now with say Scopus but the ML stuff was really handy. Google scholar doesn't have any such tags or topics fields unfortunately.
