This dropdown property is displayed just below a NoSQL selection rule’s header.

It allows you to define how a NoSQL selection rule’s criteria are to be treated when a rule’s count is generated. Two options are available – All (the default) and Any.
If All/Any is set to All, for a record to be targeted, all criteria in the rule must be satisfied. If set to Any, any one of the criteria needs to be met for the rule to be satisfied.
Note that All/Any is always displayed, even if a NoSQL selection rule contains only a single criterion. In this case it has no effect.
All/Any is also shown at a criteria list, to determine how the criteria listed therein are to be treated at the parent rule’s execution.
