Search for an Internet radio station in iTunes?

I want to search for specific Internet radio stations in the iTunes list of stations in Internet Radio. To the best of my knowledge, the iTunes search function does not support searching in the category Internet Radio. Some have suggested creating a playlist containing all the Internet Radio stations listed in iTunes and searching the playlist. I did that but still no search function. Is there ANY way to search for specific Internet Radio stations in iTunes? Browsing over 9,000 entries makes no sense. (I am running the current version of iTunes (12.8.2.3) on my Mac.
