If this option is set to False and you have defined multiple data sources and a search returns results from more than one source, the results are displayed in source order.
To display search results in one sorted list, set this option to True. If enabled,, multiple primary data sources are searched asynchronously. Secondary searches are dependent on the results of the primary data sources they are associated with, and will run as soon as the results are returned from that primary. The secondary searches will not wait for the results of other primary data sources before initiating.
If this option is set to True, the MPE device will only send SNR (Subscription-Notifications-Requests) messages to data sources when a policy is executed that includes the policy action enable subscription for notification of user profile changes. If the option is set to False, you can enable subscriptions by setting the appropriate Subscribe options (see Configuring MPE Protocol Options).
