I still prefer the option offered by Android studio, but maybe you are not looking at it. I provide screenshots of how you simply specify the file types in filer on , speed up the search process and get exactly the same files that you require .
Step .1 Specify the types of files required. Select the file types you do not want. I always save Java and xml only in Android project.

Step 2. Start the search.

Step 3 : Enjoy :-)
