Conditions within a rule are combined by applying either the ALL or the ANY matching option.

• ALL
  If the ALL option is applied, only those contacts that match all of the conditions that make up the rule are selected. The result is similar to applying an AND logical operator.
• ANY
  If the ANY option is applied, any contacts that match at least one of the conditions that make up the rule are selected. The result is similar to applying an OR logical operator.
