@shubham.pawar thanks for sharing the feedback. Would you be using this type of filter to find rows to update or would this be used a part of a typical search?

@gdj0nes Currently our use case for this filter would be to use it during a typical search; to find similar records where a particular metadata is absent.

Got it thanks for sharing!
