Negated operators—such as <>, Not In, Not Under, Not In Group—tend to generate nonselective queries and large result sets.Only use negated operators when necessary. Always try to find alternatives first. For example, if Field1 has values A, B, C, D; specify the Field1 In A, B,...

The % character represents any character sequence. This example restricts the query result to allAuthors with afirstNamethat contains the String ‘and’, like Alexander or Sandra. You can use an_instead of%as a single character wildcard. You can also negate the operator withNOTto exclude all...
PFCG conditions with empty parentheses on the left side cannot be negated using the operator NOT, since this entails the opposite of an authorization check and hence unexpected results.PFCG conditions can be combined within an access rule using literal conditions, user conditions, and inheritance ...
