Music Search worse than iTunes Search

I am a pro DJ, I used to organize all my music in iTunes which was the center of everything, the point of union between the various apps such as Pioneer Rekordbox or Native Instruments Traktor.

Now, with the Music app, things are much more difficult than before, especially the Search, it's really difficult for me to search for a song especially in my main Songs list or in a wide playlist, before it was much easier.
