I don't even trust the "turn off" buttons.
I just write my own utilities. They're simple to write, they work, and I port them around as needed.
P.S. I have file indexing turned off on my drives.
I don't use such apps, not because I don't like them, but because these days I just don't trust them to not surreptitiously send an index of my system to them.
I wrote my own file search programs. It's not hard, just a few lines of code. I use them every day.
