I habe a very special question about the VISTA rules, We are in the set-up process with adobe but for me it's not clear what the colum "not" is and why this one is needed. Anybody who can explain it? I know it's very special.
Not sure what the document is, however, it appears to be a negation column. "Contains query of a certain value" would be the positive case, and your case (the negative) is - "does not contain a query of a certain value".
