@paveltiunov can you clarify what this is fixing? The title is a little scary sounding :)

I'm looking to enable Tesseract to leverage multi-stage calculations.

[paveltiunov]

@hank-sq Great catch! It isn't security issue here. Didn't mean to scare anyone. It's just failing if you'll try to call filter with enabled tesseract. So queries won't execute in the worst case.
